    Is Java 6 completely supported?

    Carlos XXXXX Newbie

      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
      Regards

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