I also see the failures in the javac tests, simply running: >target/hdk/jdk/bin/javac HelloWorld.java shows the exception: Uncaught exception in main: java.lang.NoClassDefFoundError: javax/annotation/processing/ProcessingEnvironment ...
The problem seems to be from commit 979981 - Apply java6 patch from "[#HARMONY-6529] [jdktools]hdk javac only support compliance 1.5". When I revert the hard-coded compliance level back to 1.5 then I don't see the exception. Cath
