QuickTip: When Netbeans 6.5 Starts And Freezes Or Becomes Suddenly Slow
It mostly happens when you are playing around with configuration and modules instead of working :-) (like me now). Netbeans opens correctly all windows and freezes. Even restarting does not help. It is caused by deserialization of your last window settings, open views etc. Sometimes (e.g. after installation of a new plugin), Netbeans is no more able to restore the settings, which manifestates in stack trace similar to [./netbeans/var/log/messages.log]:
INFO [org.netbeans.core.windows.persistence]: [PersistenceManager.getTopComponentForID] Problem when deserializing TopComponent for tcID:'MultiView-PageFlow#007CXML#007C'.

at org.netbeans.modules.settings.convertors.SerialDataConvertor$SettingsInstance.instanceCreate(SerialDataConvertor.java:420)
The problem can be easily fixed by removing the particular file (MultiView-PageFlow#007CXML#007C.setting in my case), or if you are lazy, all [XYZ].setting files from: .netbeans\6.5\config\Windows2Local\Components. It will have similar effect to the "Reset Window" action.
It happens not very often: exactly 2 times in my case (after the installation of JavaFX and IceFaces extension).

Very annoying issue indeed:

I've noted that this is certainly a bug, because always that I leave opened the faces-config.xml, the next time I run netbeans, it freezes, and taking a look to the log, the exception comes up with the file you mention (MultiView-PageFlow#007CXML#007C.setting).

Hi Adam,
you are great.
I had the same problem in NetBeans IDE 6.7 (Build 200906241340) as well.
And such errors are very, very, very annoying.
So Thanks a lot!
@Varun:
No change to fix the problem online via a patch!!!!
