Product Version: NetBeans IDE Dev (Build 201002110200)
Java: 1.6.0_16; Java HotSpot(TM) Client VM 14.2-b01
System: Windows XP version 5.1 running on x86; Cp1251; ru_RU (nb)

To reproduce:
- create WeatherFXApplication sample
- open Weather.fx in editor
- invoke Format popup menu command on source

On Sun Ultra 20 (2.4 GHz Dual Core Opteron, 3GB RAM) it takes 1 min 8 sec to complete the operation. While it's in progress, IDE doesn't respond. See attached screenshot.

I use the NetBeans-JavaFX-Soma: #157 and the IDE hangs in this case.

Comment 5 Anton Chechel 2010-03-02 09:35:20 UTC 
The problem is in our slow lexer which is been invoked after every small modification of document.

It is fixed for now but there are 2 related issues left:
1. http://netbeans.org/bugzilla/show_bug.cgi?id=181436 If user has assertions enabled then he can experience assertion error during reformatting. Should be fixed in netbeans editor soon.
2. https://netbeans.org/bugzilla/show_bug.cgi?id=150197 There is still problem with performance if user invoke undo after big reformat. Should be fixed soon as well.
