Hi Ulrich,

I can't reproduce the bug and by reading dpkg-maintscript-helper I think
you are mistaken in your diagnosis.

It's the $SYMLINK and not the $SYMLINK_TARGET that has to be absolute
target, see the code. 

But it looks like the support for relative symlinks were added in
1.17.14:

dpkg (1.17.14) unstable; urgency=low
[...]
  * Add support for relative symlinks to dpkg-maintscript-helper
  symlink_to_dir
    command. Suggested by Don Armstrong <don at debian.org>.

and the ${misc:Pre-Depends} was fixed in 1.17.22:

dpkg (1.17.22) unstable; urgency=low
[...]
  * Bump minimal version for dir_to_symlink and symlink_to_dir commands
    to 1.17.14 in dpkg-maintscript-helper(1) man page. Closes: #769843

So libdb5.3-java just needs binNMU with dpkg 1.17.22.

Cheers,
Ondrej
