Re: [aspectj-users] java.lang.VerifyError: stack shape inconsistent

Thanks Andy.  That's hopefully it.  We are in fact using an IBM J9 VM.

Things were all fine with this project in the past though... but I think it was running with AspectJ RT 1.5.3.  I think it may have been the introduction of aspectjrt 1.5.4 that caused this problem to surface.  Does this make sense to you that this could / would happen?  If so, I would consider rolling back the aspectjrt upgrade, in order to resolve this issue in the shorter term, as there are other more pressing issues on my plate.

Thanks,
Bryan

Are you by any chance running on the IBM J9 VM?  If so, are you on the
latest?  For example, see

which describes how after weaving a system with ITCAM (this happens to
use AspectJ inside) you then cause the VM to throw a stack shape
inconsistent problem and the fix is to upgrade the VM.

I don't believe 'stack shape inconsistent' is due to a mismatch in
weaver/compiler versions used.  We have no open bugs on that error.
The only similar verify issues I have seen are relating to incorrect
stack height - and they are usually because CGLIB generated code is
being woven.

If it isn't a VM issue, then feel free to raise a bug and we can
investigate further.

cheers,
Andy.
