I have a fairly simple Java SE7 project with three source files. After first time the ide was restarted, the IDE now hangs at "Opening Main Window" stage.

  Product Version         = NetBeans IDE Dev (Build 201304102301) (#2ad081310c61)
  Operating System        = Linux version 2.6.32-400.1.3.el5uek running on amd64
  Java; VM; Vendor        = 1.7.0_11; Java HotSpot(TM) 64-Bit Server VM 23.6-b04; Oracle Corporation
  Runtime                 = Java(TM) SE Runtime Environment 1.7.0_11-b21
  Java Home               = /perf/pkgs/jdk/jre
