"a postgres driver which is repackaged by somebody else": These re-packaged
jar files normally contain only extra MANIFEST headers (Import-Package and
Export-Package). The bytecode and the source is the same as in the
original. Are you a contributor of PostgreSQL JDBC driver? The next version
will contain the necessary MANIFEST headers? If not, we must keep using
re-packaged jars.

"pax implementation doesn't clean up after itself": I do not think that the
one who serves DataSourceFactory should clean anything up. The pax
implementation only works as a factory. In my opinion, It is the
responsibility of the client modules to close any requested resources when
the DataSourceFactory service is unregistered.
