Product Version = NetBeans IDE 8.1 Beta (Build 201507302201)
Operating System = Windows 8 version 6.2 running on amd64
Java; VM; Vendor = 1.8.0_45
Runtime = Java HotSpot(TM) 64-Bit Server VM 25.45-b02

I was busy executing this test case:
http://services.netbeans.org/synergy/client/app/#/case/477/suite/1130/v/1

When running the new, empty NetBeans Platform Application with Felix, I get the below error. I did notice that there is nothing that according to the libraries tab of the project properties, there is no module providing javafx.application - I wonder whether that is related.
