Hi,
I've come across a strange problem when using GF3.0.1. When opening a new InitialContext() from a program I have a about 80% chance of getting an NPE with the following stack trace:
java.lang.NullPointerException

... 8 more
NB: My Glassfish's ORB port is at 10037.
I have distilled a simple test case which is attached. It seems that the more threads are used, the more it is likely to get above NPE. In about 20% of the time, the test executes just fine.
My environment: Glassfish 3.0.1, JDK 1.6_20, Kubuntu 10.04
For the attached test case to work there needs to be the queue "queue/myTestQueue".
Any hints are appreciated. Thanks in advance,
Chris.
