I've lived with this problem since 2008. Or even earlier. What JWM developers say about Fvwm: https://bugs.openjdk.java.net/browse/JDK-4472864 BT2:WORK AROUND Do not use fvwm 2004-06-10 19:45 Actually Sun never was able to hire qualified engineers that able to fix X Window related code. What they wrote about Fvwm: https://bugs.openjdk.java.net/browse/JDK-6586041 We should also check if FVWM follows ICCCM specification, in particular ICCCM focus model. If not, this change request may be closed as a bug in FVWM. Here more: https://bugs.openjdk.java.net/browse/JDK-6586041?jql=text%20~%20%22fvwm%22 like: I see the same focus bug when running the test with JDK 1.5.0_08 on linux. Thus, the problem is with XToolkit. My guess is that FVWM doesn't handle WM_TAKE_FOCUS correctly of doesn't use it at all. I doubt this issue will ever be fixed as FVWM is pretty old and unsupported window manager. ================================================================ I have extremely limited knowledge on X Window API and Fvwm internals. I would like to stay with Fvwm 2 unless new API made it unusable. I tried brief search for Java workarounds in Gnome shell, openbox and fluxbox sources. At least to find out what is special in handling of Java app. But I haven't found anything related so far. Inside VirtualBox VM OpenBox WM is able to pass keyboard focus to Java app but Fvwm isn't. Following: Style "sun-awt-X11-*" MouseFocusClickRaises, Lenience only help to bring Java app to foreground. -- http://defun.work/
