Code was added in version 4.2.1 to the WebAppClassLoader class to override the findClass() operation.

I have a web app that uses the sun rmi-iiop to connect to remote applications (which worked fine before). The stubs for my code are located in my deployed jars in the war.

At line 98 in WebAppClassLoader.java, a call is made to attempt to run the iiopstubcompiler. It gets a ClassDefNotFound on the IIOPStubCompiler class, which then bypasses the catch block (which is looking for a RuntimeException). It looks like the intent was to run the super.findClass() if there is any trouble, but that doesn't happen due to the catch block being bypassed.

If I change the code to catch Throwable or add a catch for ClassDefNotFound which runs super.findClass(), the app works as it did before.
