Comment 5 for bug 921831

(didn't see the request for more information, but did see the expiry notice. weird.)

"did you mess around with manual symlinks yourself?"
After I attempted to fix the problem with multiple installs of the packages suggested, I made a symlinks in /usr/local/bin/. I should hope that making a symlink in /usr/local/bin/ would not demolish the /etc/alternatives/ ecosystem.

Upgraded to 12.10 since this bug was filed. I had four alternatives for '/usr/bin/jar' after upgrading to 12.10.
Wiped them all out, removed the /usr/local/bin/ symlink. Reinstalled package 'openjdk-7-jdk' and dependencies (not recommendations nor suggestions).

$ update-alternatives --list jar
/usr/lib/jvm/java-7-openjdk-i386/bin/jar

Please mark this issue as obsolete/ already fixed.
