Re: [aspectj-users] weaving an existing jar ?

[Yang <teddyyyy123@xxxxxxxxx>]

actually I found how to do it on maven aspectj plugin page.


but now the further problem is, is it possible to weave a call from
JRE itself (System.gc() ) ?

the maven plugin only allows weaving jars and .class files

Thanks
