Re: [aspectj-dev] WeavingURLClassLoader does not follow jar Class-Paths

[Alexandre Vasseur <avasseur@xxxxxxxxx>]

Mike,

Could you describe some more your use case. We could see if it will be
adressed thru the load time weaving things that will surface in M3
(based on -javaagent for Java 5 - tell us if you would like it on 1.3
/ 1.4 ).
Perhaps the load time weaving (that will require at least a JVM
option) will be too much for what you are trying to do ?
