JVM getting crashed

Hi!

I have an application where i serialize the object and write it to a file using objectOutputStream .I use "showOpenDialog()" of fileChoser.But when my code tries to access th UI Manager or open the file Dialog,The JVM sometimes crashes and the log file it creates throws error saying :

An unexpected error has been detected by HotSpot Virtual Machine:

#

# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0333490d, pid=1112, tid=3852

#

# Java VM: Java HotSpot(TM) Client VM (1.4.2_12-b03 mixed mode)

# Problematic frame:

# C [fontmanager.dll+0x3490d]

If some one can elaborate on what to do for this,would be helpful and lot many other things are printed in the log file.I would provide the details if required to understand the problem.
