Bug description:
The virtual machine occasionally crashes with the following type of error:

#
# An unexpected error has been detected by Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00007fad1a62025a, pid=12503, tid=1107077456
#
# Java VM: Java HotSpot(TM) 64-Bit Server VM (10.0-b22 mixed mode linux-amd64)
# Problematic frame:
# V  [libjvm.so+0x1f125a]
#
# If you would like to submit a bug report, please visit:
#   http://java.sun.com/webapps/bugreport/crash.jsp
# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.
#

A current workaround is to use the 32bit virtual machine instead. It is available only for Sun's JDK. The package name is: 

ia32-sun-java6-bin

Run it from:

/usr/lib/jvm/ia32-java-6-sun

I am attaching an example error log.
