Buig 1389: Fix SIGSEGV on OpenJDK11 on [NSApplicationAWT sendEvent:]
Culprit of the crash and the non propagated action on NSApp main-thread was _simply_ our OSXUtil_KickNSApp() 'kick alive' NSApplicationDefined NSEvent sent to the NSApp. Java11's NSApp code overrides sendEvent and handles NSApplicationDefined + subtype=ExecuteBlockEvent using the given data1 as a function pointer. 8-O ExecuteBlockEvent defined as 0, which we have sent. Simply passing subtype=8888 avoids this side-effect. Whether it is still required to KickNSApp() is another question. +++ Further, make code a bit more robuts regarding the offscreenSurfaceLayer at JAWTWindow invalidate. I.e. if still not detached, do the late cleanup there. This just in case the OSX Context callback to disassociate the drawable has been missed.
