> Whenever one of the methods of a coprocessor is invoked, the context {{ClassLoader}} isn't set to be the {{CoprocessorClassLoader}}.  It's only set properly when calling the coprocessor's {{start}} method.  This means that if the coprocessor code attempts to load classes using the context {{ClassLoader}}, it will fail to find the classes it's looking for.
