>> In the scenario where AWT's UNLOCK API encounters a pendingException, the env pointer throws the pendingException (as seen in `awt.h`). However, in `Java_sun_awt_X11GraphicsDevice_pGetBounds`, after `AWT_UNLOCK`, the bounds var is set. The exception check does not occur until after the bounds is set, so the bounds may be set to an undesired value. This fix adds another exception check to look for this pendingException after `AWT_UNLOCK`.
