Tags: 2.0.3-2.2
* Non-maintainer upload.
* Fix FTBFS from -2.1: don't fail when we can't clean up the java build,
  such as when openjdk isn't installed.
* Disable parallel builds, because libtool is made of fail (if binary-arch
  and build-indep run concurrently, we relink a library while it's being
  used; that doesn't work so well).
