Re: [aspectj-users] java.lang.VerifyError: stack shape inconsistent
|
I was able to recreate the issue with the Sun JRE as well...
So, this seem like it could this be an AspectJ bug. I'm going to try to isolate the issue better.
Thanks,
Bryan

I will try to run against the Sun JRE to see if the issue still exists.

So you are now on IBM J9 1.5 SR6?
Are you able to try a one off test with a Sun vm to see if the problem
still occurs? If so, it is obviously more likely to be an AJ bug than
a VM issue.
Can you temporarily exclude the problematic method?
