Adrian Brock commented on JBAS-6834:
------------------------------------

This looks like a hack in the aspect works class.

It assumes it can use the classloader to get a resource called WEB-INF/aop.xml
from WEB-INF/classes by doing a getResources("../aop.xml")

This usage is certainly not valid, though it would work with our old URLClassLoader implementation,
it is very much relying on an implementation detail and non-spec behaviour.

In JBoss5 WEB-INF/classes is a root of the VFS so you can't "go off the top" with the .. prefix
which is what the error message says.

The aspectwerkz class with the 'hack" is this one:
http://fisheye.codehaus.org/browse/~raw,r=1.25/aspectwerkz/aspectwerkz3/src/main/org/codehaus/aspectwerkz/definition/SystemDefinitionContainer.java
I don't see anyway to override the behaviour in that class, so you need a patch to it.

getResources("aop.xml") would work in JBoss5 since WEB-INF is a root of the "classpath"
Although the correct place to put runtime resources is WEB-INF/classes which is required by
spec to be in the classpath not WEB-INF which is not.
