Hi Kabir Kahn, I'm not sure on what to change in aop. I need to start in svn.jboss.org/repos. And then what? /jbossas/projects/aop/tags/JBOSS_AOP_2_1_4_GA ? This can be retrieved by svn co https:// and the above? I already build jboss 5.1.1GA and now need to do the pluggable-instrumentor.jar thingy. How does that work. Sorry for my lack of knowledge but I'm new to this patching thing. Best regards, Werner View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4249400#...
