openjdk-9 for Debian/Ubuntu --------------------------- The OpenJDK build is configured --with-additional-vms to build with different virtual machines. The original implementation of the hotspot VM is only available on the amd64, i386, lpia and sparc architectures. Other VM's: Zero, providing a byte code interpreter for every architecture. To use a different VM other than the default, use java -zero or for the java tools, use <tool name> -J-zero. To change the default permanently, edit /etc/java-9-openjdk/jvm.cfg. The Zero VM can be found in the openjdk-9-jre-zero package (on the architectures where the Hotspot VM is available). Please look for further documentation in the directory /usr/share/doc/openjdk-9-jre/ . The package openjdk-9-jre-headless ships a cgi script /usr/lib/jvm/java-9-openjdk/bin/java-rmi.cgi that you must integrate into your webserver setup manually if you need it. It is not activated automatically. Note for non-reparenting window manager users --------------------------------------------- If you are using a non-reparenting window manager, such as ratpoison, awesome or dwm, some Java graphical applications using the AWT toolkit will only display empty grey windows, as described in but #508650. There are two solutions to work around this issue: 1. mask your window manager as one of the non-reparenting ones supported by AWT, using the wmname <http://tools.suckless.org/wmname> tool from the suckless-tools package: $ wmname LG3D 2. set the environment variable _JAVA_AWT_WM_NONREPARENTING: $ export _JAVA_AWT_WM_NONREPARENTING=true You can automate these tasks by writing them to your ~/.xsessionrc: $ cat >> ~/.xsessionrc <<EOF export _JAVA_AWT_WM_NONREPARENTING=true EOF IcedTea NPPlugin ---------------- IcedTea provides a java plugin for at least mozilla based browsers. It is not yet 100% with the closed source plugin, but much improved to the former GCJPlugin. If you experience problems with the plugin, start your browser from the command line with the environment variable ICEDTEAPLUGIN_DEBUG set, and attach this output to a bug report. You usually should not expect a quick fix, if the applet code is closed source, or only accessible after creating accounts for external web services using these applets. -- Matthias Klose <doko@ubuntu.com> Sun, 03 May 2009 13:58:10 +0200 -- Torsten Werner <twerner@debian.org> Wed, 02 Apr 2008 11:46:53 +0200
