I've tried Xvfb and Xdummy (using the sample configuration xorg.conf).
The mouse reacts as expected.
For native applications keyboard and mouse work as expected.

Got it: this is nothing new and affects all versions.
It's a focus problems which seems to prevent Java applications from gaining the window focus, you can workaround the problem by focusing away then back to the Java application - but even that is not reliable!

I had a look yesterday as well because I wanted to go back to the last working version in order to have a working keyboard.
To my astonishment the last version I had installed and worked was 0.3.2. That would confirm your observation.

I had known that problem as well but it didn't work for me yesterday.

More external pointers:
- xmonad does not follow ICCCM and ignores WM_TAKE_FOCUS protocol (Haskell - yuk!)
- qtile focus code (python)
- Keyboard focus lost in Swing applications (ex: Netbeans) after changing to window
Trying to change our code to match those examples does not solve the problem...

Re #138: I wanted to try to reverse that specific change but the code has changed significantly since then.
One new development: I've played around with the focus and it seems when a dialog window with a textbox comes up the text field won't receive keyboard input. However, when I put the main window into focus, the text field in the dialog does receive keyboard input. So far I haven't found a way to reveive keyboard input in the main window.

One more datapoint: if I use jdk6 then I have fewer focus problems and even when there are problems, clicking again on the field/area solves it.

with this patch - focus works with JDK6

With JDK6: it may even work without the patch above (not tested), and it definitely works with the patch.

I can confirm the patch works with sun jdk 6, however it doesn't work server side with jdk7 (icedtea).

This was all a wild goose chase, found the bug with good old print statements by looking at the "input" member of WMHints and noticing it was not a boolean... r2003 fixes this.
Will backport to all branches. Please confirm this works for you.
comment:12 Changed 8 years ago by
I can confirm this change works for jdk7 (icedtea) also.
Well done, thank you!

copyleft 2010 - 2021
Confirmed (tested with jedit). What is a little strange is that I can reproduce this bug with versions as old as 0.3.x, surely it hasn't been broken for that long since I remember testing some java apps (josm) with those releases..
