Thanks for the report, but I'm unable to reproduce the issue on the current build from web-main branch: Product Version: NetBeans IDE Dev (Build 20141121-ab60b41e7116) Java: 1.8.0_20; Java HotSpot(TM) 64-Bit Server VM 25.20-b23 Runtime: Java(TM) SE Runtime Environment 1.8.0_20-b26 System: Mac OS X version 10.10.1 running on x86_64; UTF-8; en_US (nb) Moreover this issue wasn't caused by any of the JavaFX support modules. Please try again later with the next dev build. Thanks!
Created attachment 151951 [details] Thread dump
The issue is not reproducible in 8.0.2, only in the current dev builds. Could server split affect this?
Issue is not reproducible anymore on: Product Version: NetBeans IDE Dev (Build 20150330-2f86cb365e7c) Java: 1.7.0_75; Java HotSpot(TM) 64-Bit Server VM 24.75-b04 Runtime: Java(TM) SE Runtime Environment 1.7.0_75-b13 System: Mac OS X version 10.10.2 running on x86_64; UTF-8; en_US (nb)
