Thread Dump

Whenever I press a button that requires opening a File Chooser, the CPU spikes and netbeans is locked (no repaint) for a period of time, often up to 5 minutes.  This happens every time Open Project, or selecting jars to add to a project library.

I am connected to VPN, have mapped drives to work, and a disk that points to a etx3 partition.  I've tried unmapping drives, but that doesn't effect it.

You hit the now famous JDK problem, see http://wiki.netbeans.org/FaqWindowsCPU for explanations and possible workarounds.
