Well.. `realSync()` works here but I am not sure if that invocation really
fixes the issue or just hides it by introducing a delay.
I believe we need some function which ensures that the frame is in correct
(`NORMAL`) state right after `unmaximize()` call and before
`execute(CWrapper.NSWindow::miniaturize)` invocation.
Possible implementation of that method below:
private void waitForWindowState(int state) {
Object lock = new Object();
target.addWindowStateListener(new WindowStateListener() {
public void windowStateChanged(WindowEvent e) {
synchronized(lock) {
if (e.getNewState() == state) {
lock.notifyAll();
}
}
}
});
if (peer.getState() != state) {
synchronized(lock) {
try {
lock.wait();
} catch(InterruptedException ie) {}
}
}
}
So in code you will call `waitForWindowState(Frame.NORMAL)` instead of
`realSync()`
