    Description

      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.
