The test could be minimized to only two important tests - Robot GUI and AwtMemoryLeak GUI. AwtMemoryLeak performs Widget corruption, while Robot detects that corruption. 2.In AwtMemoryLeak test, the most important is DialogTest - this test shows and disposes dialog. I didn't see any problem with FrameTest or WindowTest. 3. When test first disposes Dialog then owning Frame, on native level we see that for Dialog both Dialog AWT native data are being destroyed and then widget destroy callback is being called. After that, if everything is correct, the same should happend with frame. However, what happens is that Frame's widget becomes destroyed along with Dialog's widget without corresponding call to Frame's dispose and this leaves stale Frame widget in our top-level list and this is the widget which is being accessed from, for example, awt_WidgetAtXY. I've not yet found who destroys Frame's widget. ###@###.### 2002-06-11 ====================================================================== Name: dmR10075 Date: 06/13/2002 The bug was caused by the fix: D 1.77.1.3 02/03/21 10:44:24 pz71691 175 173 00222/00126/04002 MRs: ====================================================================== Name: dmR10075 Date: 06/13/2002 The bug was caused by the fix: D 1.77.1.3 02/03/21 10:44:24 pz71691 175 173 00222/00126/04002 MRs: >COMMENTS: Fixed 4511021 - Revisit how KeyboardFocusManager clears its fields 4483839 - Memory leak in DefaultKeyboardFocusManager 4604625 - windowLostFocus & windowDeactivated events are not triggered for Frame.dispose() Fixed by Oleg Sukhodoslky (###@###.###) Reviewed by Michael Martak, Michael Bronson, Valeriy Ushakov(###@###.###) in file awt_TopLevel.c We decided to delay the destruction of top-level widgets until after all pending X events will be processed. However, some top-levels we dispose at once. In our case, the test first disposes Dialog then Frame. Dialog has X window so we delay its disposal. Frame doesn't have X window so we dispose it at once, and because Dialog's transient shell is a child of Frame's shell Xt destroy Dialog's shell as well leaving our internal structures unupdated. ###@###.### 2002-06-13 ======================================================================
