Re: [aspectj-dev] Generic Aspects in M4
|
Strange that it complains about java.lang.StringBuilder missing -
definetly running the compiler on top of a 1.5 VM? I think pointcuts
were pretty much finished in terms of generics for M4, ITDs were not.
If you want to play about a bit, you could prevent it (with withincode
or something) attempting to weave the onException() method that uses
the stringbuilder class...
