Carol Frampton commented on FLEX-33155:
---------------------------------------
http://www.oracle.com/technetwork/java/javase/compatibility-417013.html#source
Area: API: Utilities
Synopsis: Updated sort behavior for Arrays and Collections may throw an
IllegalArgumentException
Description: The sorting algorithm used by java.util.Arrays.sort and
(indirectly) by java.util.Collections.sort has been replaced. The new sort
implementation may throw an IllegalArgumentException if it detects a Comparable
that violates the Comparable contract. The previous implementation silently
ignored such a situation.
If the previous behavior is desired, you can use the new system property,
java.util.Arrays.useLegacyMergeSort, to restore previous mergesort behavior.
Nature of Incompatibility: behavioral
RFE: 6804124
> Uncaught exception in compiler, when JRE 1.7 is used
> ----------------------------------------------------
>
> Key: FLEX-33155
> URL: https://issues.apache.org/jira/browse/FLEX-33155
> Project: Apache Flex
> Issue Type: Bug
> Components: Compiler API
> Affects Versions: Apache Flex 4.8 (parity release)
> Environment: JRE version 1.7.0_05 , FlashBuilder 4.6 , Apache Flex
> 4.8(parity release)
> Reporter: Sudhir
> Labels: Compiler, java_1.7
> Fix For: Apache Flex 4.9.0
>
> Attachments: UncaughtException_Compiler.log
>
>
> Steps to Reproduce:
> 1. Download the Apache SDK using AIR tool (available at
> http://people.apache.org/~bigosmallm/installapacheflex/ ) which also packages
> the SDK to use with Flash builder.
> 2. Download JRE 1.7
> 3. Install Flash Builder 4.6
> 4. Go to the installed FB location and delete the JRE folder already present
> in the FB installed location
> 5. Copy the JRE 1.7 folder into the installed location. (jre folder should be
> renamed from jre7 to jre)
> FB will now use JRE 1.7 instead of using the bundled 1.6
> 6. Configure FB to use Apache SDK which was downloaded in step 1.
> 7. Create a Flex project using Apache SDK
> 8. Now create a new AS class inside the new project
> Actual result: Internal build error in problems view. The error log says that
> there was an uncaught exception in the compiler.
> Expected result: There should be no such errors
> Workaround: Add a line "-Djava.util.Arrays.useLegacyMergeSort=true" in the
> FlashBuilder.ini
> Note: This issue is specific to Apache SDK. It is working fine with the
> released version of Flex SDK 4.6
