jinfo plugin alternative should be mozilla-javaplugin.so instead of -javaplugin.so

[Kirk Steffensen]

The openjdk-6-jdk package creates /usr/lib/jvm/.java-1.6.0-openjdk.jinfo

The last line of this file defines the alternative for the Firefox java plugin
plugin -javaplugin.so /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/IcedTeaPlugin.so

Running update-java-alternatives with the original file results in an error of "update-alternatives: error: no alternatives for -javaplugin.so."

# sudo update-java-alternatives --set java-1.6.0-openjdk
update-alternatives: error: no alternatives for -javaplugin.so.

This happens because there is no /etc/-javaplugin.so alternative defined. The correct alternative is /etc/mozilla-javaplugin.so.

If you add "mozilla" to "-javaplugin.so" in /usr/lib/jvm/.java-1.6.0-openjdk.jinfo, update-java-alternatives runs correctly.
plugin mozilla-javaplugin.so /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/IcedTeaPlugin.so

Please add "mozilla" to that line when the openjdk-6-jdk package installer generates /usr/lib/jvm/.java-1.6.0-openjdk.jinfo

Please also check openjdk-7-jdk for the same issue. I am running 11.10, so icedtea7-plugin is not available for me to check if the same issue occurs with openjdk-7-jdk. Someone should check it in 12.04, where I understand icedtea7-plugin is working.

Thanks for the good work on the openjdk packages.

I just confirmed on a fresh 11.10 VM that this also affects openjdk-7-jdk.

With a fresh 11.10 installation, sudo apt-get install openjdk-7-jdk resulted in /usr/lib/jvm/.java-1.7.0-openjdk-amd64.jinfo with the following final line:

plugin -javaplugin.so /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so

Even though icedtea7-plugin isn't working in 11.10, when it does work, this line will need to read "mozilla-javaplugin.so" instead of "-javaplugin.so":

plugin mozilla-javaplugin.so /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
