Re: [aspectj-users] AspectJ class format error

[Jeffrey Sinclair <jeff@xxxxxxxxxxxxxx>]

Andy,

This is only an issue with the annotation approach, the same Aspect works
with the code style.

The class in question, SnipClass, should not have been impacted by the
Aspect. Even after adding !within(com.snip3.SnipClass) the exception still
occurs.

I'll attempt to decompile and reproduce a test case for you but it is
proving a little hard to reproduce in an isolated environment.

Regards,

Jeff
