[jboss-user] [JBoss AOP] - Re: Dynamic AOP and User-Defined Class Loader

[shu_boston]

Hi,

I tried what you said, and got a series of stack traces as below. Line 44 of test.Main.main (Main.java) invokes test.Test.print(), and the last stack trace came from RuntimeException thrown by JBoss AOP.

I'll try load-time weaving. Thanks for your advice!
