midori is not working with the java plugin on my ~amd64 system. When visiting a page with a java applet, midori tries to launch the java plugin, but it fails. In my system I have: # eselect java-nsplugin list Available 32-bit Java browser plugins Available 64-bit Java browser plugins [1] oracle-jdk-bin-1.8 current % ls -l /usr/lib64/nsbrowser/plugins total 18840 lrwxrwxrwx 1 root root 67 Dec 31 2014 javaplugin.so -> //usr/share/java-config-2/nsplugin/oracle-jdk-bin-1.8-javaplugin.so -rwxr-xr-x 1 root root 19264896 Aug 13 07:34 libflashplayer.so -rwxr-xr-x 1 root root 18672 Jul 27 10:47 libgnome-shell-browser-plugin.so % midori http://javatester.org/version.html [...] ERROR: Didn't find JVM under /usr/lib/nsbrowser/plugins WebKitPluginProcess: ../../../../src/plugin/solaris/plugin2/common/JavaVM.c:170: InitializeJVM: Assertion `foundJVM' failed. Also, loading the page https://www.whatismybrowser.com/detect/is-java-installed in Midori shows that the Java plugin is disabled. The plugin works with Firefox, although it may be necessary to give permissions to execute Java applications from the site of interest. After running the Java Control Panel (jcontrol) and adding the site http://javatester.org/ to the exception site list (in the Security tab), the plugin is successfully launched by Firefox.
you can retry with 0.5.11... but I wonder if it will work as java plugin is using nppapi and I think webkit-gtk went away from that plugins
