I had a couple (2-3) of small Java projects open and wanted to create a new Maven projects. So I went to the main menu and selected File > New Project... and the deadlock occurred.
At least the following threads are involved in the deadlock:
Folders Instance Processor

NetBeans 7.3 beta 2
JDK 1.7.0_09 64bit
Windows 7 64bit
The projects already open were:
- Java project
- Web project
Both projects are Ant-based and very small.
The Avast! antivirus software was running and broken at the time this deadlock occured - it might be that the Avast's issue influenced NetBeans execution.
