- AWT TextRenderer: Add throw new InternalError("fontRenderContext never initialized!"); FIXME!
- GLContextImpl.hasFBOImpl(): Fix serious NPE issue if extCache is null
- GLDrawableFactoryImpl.createOffscreenDrawableImpl(..):
  - Fix NPE issue w/ null drawable
  - Fix resetting GammaRamp by ensuring originalGammaRamp will be set at 1st setGammaRamp(..)

- AndroidGLMediaPlayerAPI14: Fix NPE: Use already resolved local referenced
- EGLDrawableFactory: Fix NPE: Only operate on non null surface!
- ALAudioSink.dequeueBuffer(..): Only resolve releasedBuffer elements if not null
