Description

We have been having problems with classes that are returned by RPC methods not being loaded/initialized correctly. The work around has been to put in the servers, code of the form:

static

{ new FooBar(); }

// to resolve the ClassNotFoundException for class FooBar.

When I tried running under java 1.6, that stopped working because one of the classes had to be instantiated from a package that didn't have visibility to create an instance. So I tracked the problem down to how the classes were being loaded via reflection.
