Quitting Mac Glass application throws exceptions (ES2, J2D) and crashes Java (J2D)

When running a Glass application on Mac, if one selects the menu item

java -> Quit Glass Application

or uses the Command-Q keyboard shortcut, the exceptions are thrown for both the ES2 and J2D pipelines and Java crashes for the J2D pipeline. This was observed for both apps/internal/MediaPlayer and apps/internal/WebMap so it is not a Media issue.
