// -----
//
// **What is the expected output? What do you see instead?**
//
// The problem is that it's including the constant "1" and "2" inside the try block when the shouldn't be. When executed uncompiled, the script prints "1212". When compiled, the script prints "undefinedundefined".
//
// This behavior doesn't happen if the entire function gets inlined, or if the code between the two try blocks is sufficiently complex.

} | // You are a professional Java test case writer, please create a test case named `testWith3` for the issue `Time-88`, utilizing the provided issue report information and the following function signature.
// ## Issue-ID: Time-88
//
// ## Issue-Title:
// Constructing invalid Partials
//
// ## Issue-Description:
// Partials can be constructed by invoking a constructor `Partial(DateTimeFieldType[], int[])` or by merging together a set of partials using `with`, each constructed by calling `Partial(DateTimeFieldType, int)`, e.g.:
//
//
//
// ```
// Partial a = new Partial(new DateTimeFieldType[] { year(), hourOfDay() }, new int[] { 1, 1});
// Partial b = new Partial(year(), 1).with(hourOfDay(), 1);
// assert(a == b);
// ```
//
// However, the above doesn't work in all cases:
//
//
//
// ```
// new Partial(new DateTimeFieldType[] { clockhourOfDay(), hourOfDay() }, new int[] { 1, 1}); // throws Types array must not contain duplicate
// new Partial(clockhourOfDay(), 1).with(hourOfDay(), 1); // #<Partial [clockhourOfDay=1, hourOfDay=1]>
// ```
//
// I suppose the Partials should not allow to be constructed in either case. Is that right?
//
//
// There's also a related issue (probably stems from the fact that the Partial is invalid):
//
//
//
// ```
// new Partial(clockhourOfDay(), 1).with(hourOfDay(), 1).isEqual(new Partial(hourOfDay() ,1).with(clockhourOfDay(), 1)) // throws objects must have matching field types
// ```

## Issue-ID: Time-88
## Issue-Title:
Constructing invalid Partials
## Issue-Description:
Partials can be constructed by invoking a constructor `Partial(DateTimeFieldType[], int[])` or by merging together a set of partials using `with`, each constructed by calling `Partial(DateTimeFieldType, int)`, e.g.:
```
Partial a = new Partial(new DateTimeFieldType[] { year(), hourOfDay() }, new int[] { 1, 1});
Partial b = new Partial(year(), 1).with(hourOfDay(), 1);
assert(a == b);
```
However, the above doesn't work in all cases:
```
new Partial(new DateTimeFieldType[] { clockhourOfDay(), hourOfDay() }, new int[] { 1, 1}); // throws Types array must not contain duplicate
new Partial(clockhourOfDay(), 1).with(hourOfDay(), 1); // #<Partial [clockhourOfDay=1, hourOfDay=1]>
```
I suppose the Partials should not allow to be constructed in either case. Is that right?
There's also a related issue (probably stems from the fact that the Partial is invalid):
```
new Partial(clockhourOfDay(), 1).with(hourOfDay(), 1).isEqual(new Partial(hourOfDay() ,1).with(clockhourOfDay(), 1)) // throws objects must have matching field types
```
```
You are a professional Java test case writer, please create a test case named `testWith3` for the issue `Time-88`, utilizing the provided issue report information and the following function signature.
```java
public void testWith3() {

Hi guys,
I'm working on a project where I have to parse `2016-01-11T11:06:14.000-02` to java.util.Date which is a valid date according to [RFC3339](https://www.ietf.org/rfc/rfc3339.txt) on page 12.
But I got an Exception trying to archive it

## Issue-ID: Closure-668
## Issue-Title:
goog.addSingletonGetter prevents unused class removal
## Issue-Description:
**What steps will reproduce the problem?**
// ==ClosureCompiler==
// @compilation\_level ADVANCED\_OPTIMIZATIONS
// @output\_file\_name default.js
// @use\_closure\_library true
// @formatting pretty\_print,print\_input\_delimiter
// @warning\_level VERBOSE
// @debug true
// ==/ClosureCompiler==
goog.provide('foo');
var foo = function() { this.values = []; };
goog.addSingletonGetter(foo);
foo.prototype.add = function(value) {this.values.push(value)};
**What is the expected output? What do you see instead?**
Expect: The code is completely removed.
Instead:
(function($ctor$$) {
$ctor$$.$getInstance$ = function $$ctor$$$$getInstance$$() {
return $ctor$$.$instance\_$ || ($ctor$$.$instance\_$ = new $ctor$$)
}
})(function() {
});

## Issue-ID: Codec-CODEC-98
## Issue-Title:
Base64InputStream causes NullPointerException on some input
## Issue-Description:
Certain (malformed?) input to Base64InputStream causes a NullPointerException in Base64.decode.
The exception occurs when Base64.decode is entered with the following conditions:
* buffer is null
* modulus is 3 from a previous entry.
* inAvail is -1 because Base64InputStream.read reached EOF on line 150.
Under these conditions, Base64.decode reaches line 581 with buffer still null and throws a NullPointerException.
Here is some input data that will trigger it:

// ## Issue-Title:

// ## Issue-Description:
// Looks like calling `writeString()` (and perhaps other scalar write methods) results in writing invalid output, instead of throwing an exception. It should instead fail; in future we may want to consider allowing this as an alias, but at any rate it should not produce invalid output.

## Issue-ID: JacksonDatabind-793
## Issue-Title:
readTree does not work with defaultTyping enabled but no type info provided
## Issue-Description:
I have enabled `defaultTyping`, and serialized `Foo` entity with no type info. I'm trying to read json as a tree with `mapper.readTree(json)`, and it throws an exception
```
Exception in thread "main" com.fasterxml.jackson.databind.JsonMappingException:

```
However, if I disable `defaultTyping`, the same code works fine. So, `readTree(json)` does not actually need type info for the root element, because it works when `defaultTyping` is disabled (i.e. `{"bar" : "bar"}`), but it throws the exception when `defaultTyping` is enabled, that's why it looks like a bug. The same thing happens for `valueToTree(foo)`.
Jackson version is `2.5.3`

Even removing the year component with .withYearsRemoved() throws the same exception:
this works:
```
Period p = new Period(new DateTime(startDate.getTime()), new DateTime(endDate.getTime()), PeriodType.standard()).normalizedStandard(PeriodType.standard());
return p.getMonths();
```
this fails:
```
Period p = new Period(new DateTime(startDate.getTime()), new DateTime(endDate.getTime()), PeriodType.standard().withYearsRemoved()).normalizedStandard(PeriodType.standard().withYearsRemoved());
return p.getMonths();
```
```

// http://code.google.com/p/closure-compiler/source/detail?path=/trunk/src/com/google/javascript/jscomp/Compiler.java&r=1824
//
// What we are looking for is a way to sort dependencies and concatenate all files in their dependent order without removing the goog.require/goog.provide js calls. Turning closurePass to true causes the goog calls to be replaced. We use this methodology in local development to test our JS code.
//
// Thanks!

} | // You are a professional Java test case writer, please create a test case named `testToPeriod_fixedZone` for the issue `Time-113`, utilizing the provided issue report information and the following function signature.
// ## Issue-ID: Time-113
//
// ## Issue-Title:
// #113 Duration.toPeriod with fixed time zones.
//
//
//
//
//
// ## Issue-Description:
// I have a question concerning the conversion of a Duration to Period. I'm not sure if this is a bug, or if there is a different way to do this.
//
//
// The basis of the problem, is that using Duration.toPeriod() uses the chronology of the default time zone to do the conversion. This can cause different results from a timezone with DST and one without. This can be reproduced easily with this test.
//
//
//
// ```
// //set default time zone with this argument -Duser.timezone="GMT"
// public void testForJodaForum()
// {
// System.out.println("Timezone: " + DateTimeZone.getDefault());
//
// //Duration of more than 24 hours
// Duration aDuration = new Duration(DateTimeConstants.MILLIS\_PER\_HOUR \* 30 + DateTimeConstants.MILLIS\_PER\_MINUTE \* 50
// + DateTimeConstants.MILLIS\_PER\_SECOND \* 14);
//
// System.out.println("Duration before: " + aDuration);
// Period period = aDuration.toPeriod();
// System.out.println("Period after: " + period);
// }
//
// ```
//
// A fixed time zone produces this output
//
// Timezone: Etc/GMT
//
// Duration before: PT111014S
//
// Period after: P1DT6H50M14S

// The javadoc of toPeriod() states that only precise fields of hours, minutes, seconds, and millis will be converted. But for a fixed timezone, days and weeks are also precise, which is stated in the javadoc for toPeriod(Chronology chrono). In our app, we need consistent behavior regardless of the default time zone, which is to have all the extra hours put into the hours bucket.

## Issue-ID: Time-113
## Issue-Title:
#113 Duration.toPeriod with fixed time zones.
## Issue-Description:
I have a question concerning the conversion of a Duration to Period. I'm not sure if this is a bug, or if there is a different way to do this.
The basis of the problem, is that using Duration.toPeriod() uses the chronology of the default time zone to do the conversion. This can cause different results from a timezone with DST and one without. This can be reproduced easily with this test.
```
//set default time zone with this argument -Duser.timezone="GMT"
public void testForJodaForum()
{
System.out.println("Timezone: " + DateTimeZone.getDefault());
//Duration of more than 24 hours
Duration aDuration = new Duration(DateTimeConstants.MILLIS\_PER\_HOUR \* 30 + DateTimeConstants.MILLIS\_PER\_MINUTE \* 50
+ DateTimeConstants.MILLIS\_PER\_SECOND \* 14);
System.out.println("Duration before: " + aDuration);
Period period = aDuration.toPeriod();
System.out.println("Period after: " + period);
}
```
A fixed time zone produces this output
Timezone: Etc/GMT
Duration before: PT111014S
Period after: P1DT6H50M14S
A DST time zone produces this output
Timezone: America/Chicago
Duration before: PT111014S
Period after: PT30H50M14S
In the joda code, Duration.toPeriod() uses a period constructor that takes the chronology, but null is passed in, so the chronology of the default time zone is used, which leads to this behavior.

// ## Issue-ID: JacksonCore-152
//
// ## Issue-Title:
// What is the maximum key length allowed?
//
// ## Issue-Description:
// I noticed that even in Jackson 2.4, if a JSON key is longer than 262144 bytes, ArrayIndexOutOfBoundsException is thrown from TextBuffer. Below is the stack trace:
//
//
//
// ```
// java.lang.ArrayIndexOutOfBoundsException
// at java.lang.System.arraycopy(Native Method)
// at com.fasterxml.jackson.core.util.TextBuffer.expandCurrentSegment(TextBuffer.java:604)
// at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.addName(UTF8StreamJsonParser.java:2034)
// at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.findName(UTF8StreamJsonParser.java:1928)
// at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.parseLongFieldName(UTF8StreamJsonParser.java:1534)
// at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.parseMediumFieldName(UTF8StreamJsonParser.java:1502)
// at com.fasterxml.jackson.core.json.UTF8StreamJsonParser._parseFieldName(UTF8StreamJsonParser.java:1437)
// at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.nextToken(UTF8StreamJsonParser.java:668)
// ... <below are our code> ...
//
// ```
//
// Looking at TextBuffer.expandCurrentSegment(TextBuffer.java:604), once the length of \_currentSegment is increased to MAX\_SEGMENT\_LEN + 1 (262145) bytes, the newLen will stay at MAX\_SEGMENT\_LEN, which is smaller than len. Therefore System.arraycopy() will fail.

## Issue-ID: JacksonCore-152
## Issue-Title:
What is the maximum key length allowed?
## Issue-Description:
I noticed that even in Jackson 2.4, if a JSON key is longer than 262144 bytes, ArrayIndexOutOfBoundsException is thrown from TextBuffer. Below is the stack trace:
```
java.lang.ArrayIndexOutOfBoundsException
at java.lang.System.arraycopy(Native Method)
at com.fasterxml.jackson.core.util.TextBuffer.expandCurrentSegment(TextBuffer.java:604)
at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.addName(UTF8StreamJsonParser.java:2034)
at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.findName(UTF8StreamJsonParser.java:1928)
at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.parseLongFieldName(UTF8StreamJsonParser.java:1534)
at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.parseMediumFieldName(UTF8StreamJsonParser.java:1502)
at com.fasterxml.jackson.core.json.UTF8StreamJsonParser._parseFieldName(UTF8StreamJsonParser.java:1437)
at com.fasterxml.jackson.core.json.UTF8StreamJsonParser.nextToken(UTF8StreamJsonParser.java:668)
... <below are our code> ...
```
Looking at TextBuffer.expandCurrentSegment(TextBuffer.java:604), once the length of \_currentSegment is increased to MAX\_SEGMENT\_LEN + 1 (262145) bytes, the newLen will stay at MAX\_SEGMENT\_LEN, which is smaller than len. Therefore System.arraycopy() will fail.
I understand it is rare to have key larger than 262144 bytes, but it would be nice if
* Jackson explicitly throw exception stating that key is too long.
* Document that the maximum key length is 262144 bytes.
OR
* Update TextBuffer to support super long key.
Thanks!
