Product Version = NetBeans IDE 7.2 (Build 201207171143)
Operating System = Windows 7 version 6.1 running on amd64
Java; VM; Vendor = 1.7.0_07
Runtime = Java HotSpot(TM) 64-Bit Server VM 23.3-b01
My Netbeans 7.2 installation freezes several times a day, I have to kill the process in the task manager/process explorer. I have to switch back to 7.1 as I cannot work like that; although when 7.2 is not freezed, it is indeed faster than 7.1.
It seems to me that Nebeans 7.2 has some problems with the multithreading as mostly it freezes when it executes some task (e.g. building or testing) and I start doing something else (like opening a context menu or doing refactoring).
I also tried it with JDK 1.6.0_35 but faced the same problems.

Thanks for the report. The log file does not show anything seemingly related to the freezes. To be able to track down the source of your problem we need more information. Please provide especially the thread dump, for details see
It might well be the case that some of non-default modules cause the problem. Before we get more detailed information we can not proceed here so I am closing the bug for the moment. Please reopen when esp the thread dump is available.
By chance I found the error message that the PermGen Space is out of memory. I increased it by adding "-J-XX:MaxPermSize=256m" to the parameter "netbeans_default_options" in file "etc/netbeans.conf".
Until now, my NetBeans does not freeze any more. Maybe you give a hint on this in the installation instructions?
