11 _and_ its default SDK 'macosx10.15'
This patch demonstrates that using the SDK 'macosx10.11' does not cause the crash @ -[NSOpenGLContext setView:].
SDK 'macosx10.15' enforces Apple's own Cargo Cult of 'main-thread' by throwing a SIGILL signal (or SIGABRT)
- essentially an exception.
This surely renders our code officially invalid due to this policy,
i.e. we are not allowed to issue [* setView] on any non main-thread.
+++
The crash occurs independently of used Java version on Java 8 - 11,
as well as on JogAmp 2.3.2 - current master tip.
+++
The initial remedy to issue said action on the main-thread in a blocking/wait
manner has the risk to deadlock, due to
1) [NSOpenGLContext setView:] itself using a mutex (Thanks to Ken Harris's analysis)
and
(2) in case where we are 'thread hopping':
- [main-thread] Event like 'window ready' -> kick off action on EDT-thread *blocking*
- [EDT-thread] Create stuff incl OpenGLContext -> kick off setView on main-thread *blocking*
This has to be further investigated.
This crash finally has been reliably reproduced now.

latest tip using XCode 11
Changes to test
- Using own 'NSApplicationMain' entry to avoid the 'missing Info.plist' message!
- Configurable CLASSPATH and LIBPATH at compile time.
Note that the java.library.path is now hardcoded as well.
- Don't close stderr in test, just fflush
- Don't close the JVM after launch via 'die(env)', let it run.
- Java: Add GLEventListener RedSquareES2 to see something in action @ 30fps
- Java: GLCanvase visible bounds

using XCode 11 and JOGL 2.3.2 as well as current tip
This change imports '[email protected]' patch as
reported and provided in Bug 1398.
I can not execute this patch properly,
as received a error message regarding missing Info.plist at start.
