-------------------------------------
Determined work around to IBM JDK issue.
In Apache Geronimo GShell

Apply the following modification:
bash-2.05a$ svn diff

I have not determined how or why the IBM JDK passes in a null handler to
Descriptor - the call to the Descriptor constructor may occur in dynamically
generated code. I do know however that if we test for the null handler in the
constructor and upon detection set it to 'Handler.class' as a safe default
value that "null" error we see when executing "log d" or "config list" stops
occuring.
Will create a JIRA and attach patch to Gernimo GShell project.
