I wanted to change the editor font's size so I did the following: 1) Opened the Options dialogue. 2) Selected category "Fonts & Colors". 3) In the row labelled "Font:", I clicked on the button with ellipsis ([...]). Immediately after that, the IDE hang. JStack detected two threads involved in the deadlock - see below. I will attach a full thread dump (produced with "jstack").

It looks like a problem in KeybindingsInjector. I could not reproduce it though. Product Version: NetBeans IDE Dev (Build 080804) Java: 1.6.0_10-ea; Java HotSpot(TM) Client VM 11.0-b11 System: Linux version 2.6.22-15-generic running on i386; UTF-8; en_US (nb) Userdir: /home/vita/devel/netbeans/main2/nbbuild/testuserdir
Should be better now. http://hg.netbeans.org/main/rev/1dcd3f57c136
