Many thanks for the proposed patch. It seems we need a decision now on
which one is actually buggy: maven-debian-helper or java-policy. I would
vote for upholding the java-policy if only the symlink placement switch
does not break anything (neither reverse dependencies not the update
mechanism). Having versionless symlinks parallels nicely lib*-dev shlib
scheme and there might be situations where this is beneficial for Java
too. Unluckily enough, there are >700 source packages now directly
affected by this [1].
