I'm not sure how calls to WLDF are added, but it is possible they were added by some other tool for manipulating byte codes (at compile time), in which case this issue is a bit more interesting (could indicate collisions with certain other AOP tools). > Just for the sake of pin pointing the source of the problem, I also used AspectJ to add code to the method. It worked fine with no errors. -- This message is automatically generated by JIRA.
