Getting some interesting output on master

[Tom Schindl]

Hi,

I'm getting some interesting outputs/errors when running on 8u-dev/rt:

a) When I shutdown i sometimes get
> Java has been detached already, but someone is still trying to use it at -[GlassRunnable run]:/Users/tomschindl/Documents/e-workspaces/OpenJFX-master/modules/graphics/src/main/native-glass/mac/GlassApplication.m:92
> Java has been detached already, but someone is still trying to use it at -[GlassRunnable dealloc]:/Users/tomschindl/Documents/e-workspaces/OpenJFX-master/modules/graphics/src/main/native-glass/mac/GlassApplication.m:106

b) Also on shutdown I got (just once)
> java.lang.NullPointerException
> 	at com.sun.glass.ui.Application.invokeLater(Application.java:472)
> 	at com.sun.javafx.tk.quantum.QuantumToolkit.postPulse(QuantumToolkit.java:396)
> 	at com.sun.javafx.tk.quantum.QuantumToolkit.lambda$12(QuantumToolkit.java:300)
> 	at com.sun.javafx.tk.quantum.QuantumToolkit$$Lambda$42/435457674.run(Unknown Source)

Anyone else ever seen those? I'm currently working on DnD so this might
be involved but I'm not able to reproduce is all time.
