Java SE (Java Platform, Standard Edition)

My java application hangs in a windows xp machine with jre 1.5. But it works fine in windows 2000 and in some other windows xp machine.

I am doing UI updates(like custom listmodels) inside the user spawn thread. I read from forums that we need to use SwingUtilities.invokeLater() in such cases. But how it then works in some windows xp machines and windows 2000 ? Am I missing anything.

Here is the thread dump :
