Hello Andrius, hi Alexandre,

I can't speak to every reverse dependency, but I don't expect breakage
to occur with this change, assuming of course that the update mechanism
works consistently.  I also agree with you that a versionless symlink to
a versioned jar file seems preferable.  As you mention, if nothing else,
it is consistent with other languages in Debian.  So my vote is to
accept the change.

That fact that so many packages are affected does mean there will be a
lot of uploads, but ideally we will upload at least once per release
cycle (anyway), so the timing of this patch and proposal is reasonable.

I am interested to hear other opinions from the Debian Java Team.

Cheers,
tony
