Bug Description

the ubuntu packages for java install to /usr/lib/jvm using a pattern like this :

java-6-sun (symlink)
java-6-sun-1.6.0.03

However, proper jvm detection is done using the pattern

jdkVERSION
jreVERSION

Second problem, the directory is named [...].0.03 where the convention seems to be to use an underscore.

so at the very least there should be a symlink jre1.6.0_03 to java-6-sun-1.6.0.03

This will make the following command work correctly :

$ java -version:1.6+ -version

java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Server VM (build 1.6.0_03-b05, mixed mode)

instead of:
Unable to locate JRE meeting specification "1.6+"

where is this naming convention used/followed?

I am trying to find information about this but it's very scarce. I think I will have to look at the actual source code for the launcher.

I can only tell you the actual "behavior" for now. If the directory has the right name, java picks it up.

"-version:1.6+" is documented by Sun somewhere - I haven't looked at it for a year or more now. Hmm - http://java.sun.com/javase/6/docs/technotes/tools/solaris/java.html has a little bit about it.

It documents the option's format, not the actual process of locating the jvm though.
that's what I'm looking for
