A DESCRIPTION OF THE PROBLEM :
I've installed the latest oracle JRE on my macbook but I can't get our rcp/swt application to start over jnlp.

The app start crashes with
!ENTRY org.eclipse.osgi 4 0 2014-09-13 19:35:07.912
!MESSAGE Application error
!STACK 1
org.eclipse.swt.SWTException: Invalid thread access

I've found a load of threads with this problem - all with the same solution: add -XstartOnFirstThread to the java-vm-args

According to the jnlp syntax (http://docs.oracle.com/javase/7/docs/technotes/guides/javaws/developersguide/syntax.html) this argument seems to be "insecure" and I think therefore the app crashes because the argument is not passed to the vm.

So I've tried to run the jnlp with latest jre from apple and the app started as expected.
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Commands/java -version
java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)

So I think this is a problem of the jre maybe only because -XstartOnFirstThread is not declared as a secure argument.
