Is Java 6 completely supported?

memeplex Mar 30, 2008 6:39 AM

I'm running into issues like

"""
Caused by: java.lang.ArrayIndexOutOfBoundsException: 5
at javassist.bytecode.StackMapTable$Walker.sameLocals(StackMapTable.java:240)
at javassist.bytecode.StackMapTable$Walker.stackMapFrames(StackMapTable.java:198)
"""

when instrumenting java 6 classes. The same classes compiled as java 5 are instrumented just fine.

I have seen similar reports in the jboss aop list. In general, the suggestion is to stick to java 5 for the time being.

So what is the status of java 6 support?

TIA

I just discovered a similar problem. Someone wanted to recompile javassist code compile with java 6.
