Re: [aspectj-users] AspectJ class format error
|
Could be an AspectJ bug. I'm not sure which method in SnipClass has
had code added to it and whether the AspectJ compiler was responsible
for it - do you think SnipClass should be woven? Are you able to see
which method in SnipClass has been affected, by using javap? Is the
code that has been added refering to methods recognizable as AspectJ
constructs? (eg. calling methods starting ajc$)
Have you tried the aspect as a code style aspect as opposed to an
annotation style one?
