how to resolve java.lang.NoClassDefFoundError: sun/reflect/GeneratedConstructorAccessor1 error

[Pooja Aggarwal]

Hi,

I am trying to use deuce STM in my existing program. I have annotated my function with @Atomic . Doing so generated the error mentioned below. Please help in solving this. If i remove @Atomic then the code is working.

if you want Deuce to support classes from rt.jar you need to annotated it offline. See documentation.
