The log file that is saved when I attempt to run a simple swing application with the JAW installed

Using Ubuntu 9.10 (Karmic Koala)
JDK 1.6.0.15

When I attempt to launch a simple Java application that has a swing GUI I very frequently get the following error output from the JRE and the Java program fails to run;

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0xb76d6d1d, pid=4028, tid=3064040304

# JRE version: 6.0_15-b03
# Java VM: Java HotSpot(TM) Server VM (14.1-b02 mixed mode linux-x86 )
# Problematic frame:
# C  [libpthread.so.0+0x7d1d]  pthread_mutex_lock+0x1d

# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.

Occasionally the same program will run correctly but I would say only about 3 times in every 10 attempts do programs run correctly.

I am attaching the log file that is produced when the error occurs.
