Hi! I'm using JBoss AOP (1.5.5 GA) in a signed applet. And am encountering some security problems. I expect this to be due to runtime generated classes (which ofcourse don't come from any of the signed jars). In debugging this leads to the 'default' ProtectionDomain ending up in the AccessControlContext, which makes the security manager deny my code any rights other then default applet rights. I'm using the JavaBean aspect from here: http://www.damnhandy.com/?page_id=17 And the class in the stacktrace I suspect is causing trouble is: PropertyChangeAspect34 I'd like to know why/how/where the PropertyChangeAspect## classes are generated when I'm using the AOP compiler (so no loadtime weaving). And I'd like to know if there's any way to work around this problem. Help? :) I'll very happily provide any additional details if needed/requested.
