[PATCH] TC4.0 - Intermittent IllegalArgumentException in WebappClassLoader

Attaching a patch that fixes an intermittent error (that occurs when an
attempt is made to define a package that has already been defined). I
noticed this when running a multi-threaded test.

----- Root Cause -----
java.lang.IllegalArgumentException: Servlet22.S05_Request
