Re: [aspectj-users] Corbetura + LTW

[Steve Ash <stevemash@xxxxxxxxx>]

Just for anyone that runs across this in the googles-- this was just
me being stupid.  I had not cleaned the workspace and the class files
that corbetura was instrumenting were already woven at compile time.
So compile time ajc -> corbetura instrumentation -> LTW caused this
blow up.  You can see the ajc stuff already in the class file that I
attached to my previous message.

Once I cleaned and re-ran letting javac build the original class files
then having corbetura instrument those and do LTW on the corbetura
classes  --- everything worked fine.

So to answer my original question -- it appears that with corbetura
2.5.1 and AspectJ Weaver 1.7.0.M1 -- LTW can weave into corbetura
instrumented classes.
