Fix synchronization issues in GLDrawableHelper.flushGLRunnables(), fixes rare deadlock with animator-exception and invoke(wait=true, ..)
Fix synchronization issues in GLDrawableHelper.flushGLRunnables():
- Querying 'glRunnables.size()' is not synchronized, only its reference is volatile,
not the instance's own states.
- 'flushGLRunnable()' must operates while acquired the 'glRunnable' lock.
- 'glRunnables' are no more volatile
- introduced volatile 'glRunnableCount', allowing 'display(..)' method
to pre-query whether blocking 'execGLRunnables(..)' must be called.
This is risk (deadlock) free.
Also fixes rare deadlock in animator display-exception / GLAD.invoke(wait=true, ..) case:
- 'GLDrawableHelper.invoke(.., GLRunnable)' acquires the 'glRunnable' lock.
- Then it queries animator state, which is blocking.
- Hence animator's 'flushGLRunnable()' call must happen outside the animator lock
