Alt+Space to open the main window's system menu doesn't work anymore. I use this all the time to minimize/close/etc. the window. This stopped working only very recently. Product Version: NetBeans IDE 7.0 RC1 (Build 201103250000) Java: 1.7.0-ea; Java HotSpot(TM) Client VM 21.0-b02 System: Windows XP version 5.1 running on x86; Cp1252; en_US (nb)
netbeans doesn't override or use this shortcut key. it doesn't work in plain swing app either (e.g. swingset demo) so it's probably jdk 7 bug
You are right, this is specific to Java 7.
Did you file it? Need jdk_bug_nnnnnnn in status whiteboard.
It had already been filed (JDK bug 6826397), and fixed this month in build b134. (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6826397)
