The bug is fixed in both JBoss AOP 1.5 and AOP 2.0 branches. To learn how to compile, refer to our wiki page http://wiki.jboss.org/wiki/Wiki.jsp?page=BuildingJBossAOPFromSubversion. After compiling, you can access the generated jars in output/lib directory. Replace jboss-aop-jdk50.jar in your jboss-aop-jdk50-deployer directory, and replace also pluggable-instrumentor file. You might also need to update other jars JBoss AOP references, but it should be fine if you use the branch equivalent to the version you downloaded. If you have any problems with deploying your compiled version to JBoss AS, let us know. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4049959#...
