FB4: Release build fails with RSLs using FlexSDK 3.5

Question

Flash Builder 4 (v 4.0.1.277662) fails, when trying to do a release build with the following simple project setup:
- Flash library project with a simple test class (using the 3.5 Flex SDK which ships with FB4)
- Flex project with simple mxml-application (using the same SDK)
  The Library is linked as RSL
When you try to export the release build of the project, you´ll get an unspecified error.
In the log file, you can found:
java.lang.NoClassDefFoundError: flex2/tools/oem/OEMException$CircularLibraryDependencyException
With some google search, I found out, that the error occured with FB 4 beta und should be already fixed.
That´s for sure true with SDK 4.0 oder SDK 4.1, but not SDK 3.5 (remember: it´s the version, which ships with the FB itself !!!).
After scanning the jar´s of the SDK 3.5 and 4.0, I found out, that the following 3 files are missing in the flex-compiler-oem.jar in SDK 3.5:
- OEMException$CircularLibraryDependencyException.class
- OEMException.class
- OEMException_en.properties
Adding these files to the jar of the 3.5 SDK, the release build will be successfully exported.
We were absolutely disappointed after realizing this issue. This has cost a lot of working time and was frustrating too.
Is there another way to get this working, without changing the SDK files?
Greetings, Jörg

Answer 1

Not sure of any workarounds apart from one what you have already tried, but can you file a Flex SDK bug for this to be fixed in the current version.
