Question

If doing System.exit(1) from a Swing application, are native resources related to the graphics automatically released ? If I add a myFrame.dispose() with myFrame being the sole
top-level container in the app, can I be sure not to get the annoying behavoiur seen in some
non-java GUI using programs where part of the GUI state will stick frozen to the screen when exiting abruptly ?

Answer 1

Everything owned by a process is released when the process exits, unless you are talking about pathological operating systems like Netware 3 & 4.
