Description Sven Gothel 2015-09-01 04:24:41 CEST
- OSX 10.10.5
- Java 1.8.0_60

Crash using CALayer at UnsetJAWTRootSurfaceLayer0(..) 
as called within MacOSXJAWTWindow.invalidateNative() (caller: destroy())
on the MainThread.

It has been observed that the 
JAWT_SurfaceLayers protocol instance 'surfaceLayers' has been pulled beforehand.

'surfaceLayers' is fetched from the locked JAWT instance
via JAWT_DrawingSurfaceInfo's platformInfo.

It now seems required to retain the instance 
at GetJAWTSurfaceLayersHandle0 and release it
at UnsetJAWTRootSurfaceLayer0 to keep it alive.

  - Fixed as described
Manually executed 'ant junit.run' on OSX, no failures or errors.
