1. The issue occurs in release mode. An incorrect style is set to Frame, but cannot be tested. --- Issue is that, The code in question should set WS_MAXIMIZE bit to 0 in window's style but in this error case, WS_MAXIMIZE bit is set to 1. Why it cannot be tested: 2. Frame.getExtendedState() always returns correct state saved in Frame.java::int state, set using setExtendedState(). 3. On native side the windows' style is accessed using GetStyle(), This style is not accessed or saved on java side. 4. When the Frame.MAXIMIZED_BOTH extended state is set while the window is not visible, the state is saved, --- on java side in Frame.java::state variable and --- on native side in awtFrame::m_zoomed variable. --- But it is not actually applied to the window, i.e. WS_MAXIMIZE bit would be 0 and we do not access the style. 5. A java.awt.event.WindowStateListener added to frame, does not receive any WINDOW_STATE_CHANGED event when a state is changed while window is not visible on screen. --- The state may not be applied when window is not visible and there is no guarantee of receiving any event when the window becomes visible and the state gets applied.
