You're right, in my previous comment I forgot about timeout.
Yet it should still be called on EDT.
However, to clean up the code a bit, I propose calling `dispose()` in finally
block. Thus there'll be only one place where frame is disposed of instead of
being scattered in multiple event handlers:
try {
// Create GUI
// Check conditions and throw exceptions on failure
} finally {
SwingUtilities.invokeAndWait(() -> {
if (frame != null) {
frame.dispose();
}
}
}
In this case, frame will be accessed from one thread only, EDT, and does not
need to be volatile.
Since the frame is always disposed of, other calls to `frame.dispose()` can be
removed.
