****************************************************************
When running an Aries application, a null pointer exception
(NullPointerException) can occur while attempting to retrieve a
system property while handling a request to a servlet in the
Aries application.

The null pointer occurs because no code source attached to a
protection domain which is used to obtain the system property.
 The system property is obtain during JNDI processing while
handling a request to a servlet of the Aries application.

The problem is a duplicate of the Eclipse bugzilla defect
282704, which was fixed in Equinox version 3.5.1.  For
more information, see the Eclipse bugzilla defect:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=282704
