Calling CGLGetCurrentContext() from the native code just before invoking JVM returns non-null GL context, however CGL.CGLGetCurrentContext() called from MacOSXExternalCGLContext returns null. Wondering why...

There must be something really weird going on since CGL.CGLGetCurrentContext() does just that - calls CGLGetCurrentContext()
