EVALUATION Name: osR10079 Date: 06/08/2004 The exception occurs somewhere in Swing. So reassign to the Swing team for initial investigation. ###@###.### 2004-06-08 ====================================================================== Name: sh120115 Date: 06/08/2004 This error is specific to the GTK L&F. Although the GTK L&F binds CTRL-space to show the system menu, it seems that it never initializes the windowMenu variable that is called upon in BasicInternalFrameTitlePane.showSystemMenu(). ###@###.### 2004-06-08 ====================================================================== windowMenu isn't used by synth because it's a menu. Instead we use a popup in synth which is what we really wanted in the first place for all the plafs. Anyway, we didn't override showSystemMenu in SynthInternalFrameTitlePane so instead we get basic's implementation which references windowMenu. The fix is pretty straight forward, override showSystemMenu in synth to do the right thing. ###@###.### 2004-06-14 The bug still reproduce on Cinnabar13/Sparc with j2sdk1.5.0-beta3-b56 ###@###.### 2004-07-06 Duplicate bug, 5046610, mentions the same problem with SHIFT-ESCAPE. ###@###.### 2004-07-09 I have verified the bug on Cinnabar20(X86&Sparc). In English local, when pressing "Ctrl+Space" there is a menu comes up and no exception. But I think when user press "Ctrl+Space", generally they want to switch input method instead of something like popup menu.Is it a new feature? ###@###.### 10/14/04 08:10 GMT
