Bug 1054: GLContext: makeCurrent() needs a null-check of [mutable] drawable; Review null checks and synchronization/locking.
'drawable' field of GLContextImpl is mutable via setGLDrawable(..), which requires high-level locking as documented. The required high-level locking allows us to _not_ add special synchronization to this field (and drawableRead). A simple null-check in makeCurrent() shall be sufficient, plus ensuring mentioned high-level locking is applied. GLContextImpl 'drawable' and 'drawableRead' synchronization: - commit ad79bd072b600a3f2416cc6f0c61e2925000069d check of null drawable is sufficient - Add GLAutoDrawable upstream-lock locking to: - AWT GLCanvas setupPrint/releasePrint - AWT GLJPanel (was missing) Misc: - validate shared-context native-surface locking, throw exception if not successful - pixelDataEvaluated does not need to be synchronized, since it's being called while context is current, locking - GLDrawableHelper.recreateGLDrawable(..): Remove redundant glFinish() call
