a ClassCastException, due to the its classes being loaded by
an unexpected classloader.

* RECOMMENDATION:                                              *
****************************************************************
ClassCastExceptions occur when the Application is running in
Single classloader policy. If a WAR module is updated the reload
code will not restart the application. A full Application
restart is required in the case where the classloader policy is
Single classloader for the complete application.
Problem conclusion
Code was updated to check the classloader policy for Single. If
it is then the application is stopped and restarted to perform
the class reload of the WAR file.
