Is this patch still necessary on OpenJDK 8?
https://git.archlinux.org/svntogit/packages.git/tree/trunk/openjdk7_nonreparenting-wm.diff?h=packages/java7-openjdk#n27

I'm having issues with window focus in Java-based GUIs (IntelliJ) under XMonad. Adding setWMName "LG3D" seems to help, but that hasn't been necessary in the past after support for "export _JAVA_AWT_WM_NONREPARENTING=1" was added to the JDK.
This task depends upon

The fix that rendered the patch obsolete, as mentioned by loqs' link, is definitely not in openjdk8: http://hg.openjdk.java.net/jdk8/jdk8/jdk/file/tip/src/solaris/classes/sun/awt/X11/XWM.java

So it looks like this should be added to our openjdk 8 package as well...

http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/tags jdk8u144-b01 is revision e95a13de2d36
http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/e95a13de2d36/src/solaris/classes/sun/awt/X11/XWM.java#l598

I was not certain about that so I checked the source arch was pulling directly

$ git clone git://git.archlinux.org/svntogit/packages.git --single-branch --branch "packages/java8-openjdk"
$ cd packages/trunk/
$ makepkg -odd
$ grep awtWMNonReparenting src/jdk8u-jdk8u144-b01/jdk/src/solaris/classes/sun/awt/X11/XWM.java
static int awtWMNonReparenting = -1;
if (awtWMNonReparenting == -1) {
awtWMNonReparenting = (XToolkit.getEnv("_JAVA_AWT_WM_NONREPARENTING") != null) ? 1 : 0;
return (awtWMNonReparenting == 1 || XWM.getWMID() == XWM.COMPIZ_WM

Seems the patch is applied

Huh... whoops. They have a very confusing mercurial setup...
