This bug happened during Sun ONE Message Queue QA testing after the test running
for > 20hrs (see below original bug report). The test has multiple threads each
creating connections then sending/receiving messages. The test run repeatly
again again. This NPE happened from java code on charset lookup for "UTF8"
- the call is originated from code like:

sometext.getBytes("UTF8")

which will be called on each connection creation.

Test Scenario
=============


Test that was run on the machin: Longevity
(http://jpgserv/JMQFalcon/qa/testcases/Longevity_Testsuite.html)

Three brokers running on Windows Linux and Solaris are clustered. The exception
occured on the client running on the Windows machine trying to connect to the
broker running on the Linux machine

Machine Configurations
======================
Sparc (Solaris 8) - Ultra 60 (hostname: colorodo)
PC Server (Windows Advanced Server) - Dual processor (two 1MHz processors),
with 512 MB RAM (hostname power-edge-2500)
PC Workstation (Redhat Linux 7.1) - Dual Processor PC (two 400 MHz processors),
with 256 MB RAM

This happens with both weblogic and websphere when using SUN and performing
Dynamic WebServices. Can this be fixed for 141_03 seems simple enough to get
and something lots of webservice users world wide will see.
