Fix for issue 1376.

With the addition of AspectJ there are some added dependencies in the code.  So
for instance using the class StaticUtils requires je.jar to be on the path
(which was not the case before).  The uninstall scripts used to have a limited
set of jar files so that afterwards there was a minimum number of files to be
deleted.  Instead of doing this uninstall scripts should use the full class path.

In any case all the remaning files are under the same directory so the user will
have to do the cleanup in the same single place as before.
