IMO, the error you're getting is unexpected. Since your ClassLoader loaded the referred class, and since the class pool is associated with this class loader, it should be able to find it. To help me track what is causing this problem, I need to know if you're using load-time weaving (without aopc) or compile time weaving (with aopc). In case you are using compile-time weaving, could you plese check: (1) if a call is being made to yourClassLoader.getResource(String)? (2); if the error happens also with load-time weaving. Thanks!
