The log says the enhancement succeeds:
2012-03-14 14:01:33,531 INFO [DataNucleus.Enhancer] - <DataNucleus Enhancer : Using ClassEnhancer "ASM" for API "JDO">

2012-03-14 14:01:34,999 INFO [DataNucleus.Enhancer] - <Writing class file "/home/www/../entity/...class" with enhanced definition>
....

But the class files seem corrupted when running a test:
Tests in error:
testAddLogon(sw.FindLoginTest): Expecting a stackmap frame at branch target 20 in method sw.entity.Login.jdoIsTransactional()Z at offset 4

Any timeline on this?

Thanks,
Mike

No estimates, and indeed no estimates are ever given for unfunded work. You could look at
http://veerasundar.com/blog/2012/01/java-lang-verifyerror-expecting-a-stackmap-frame-at-branch-target-jdk-7/
and include some obscure VM argument. Alternatively contribute time/donations for this to be done.
