Current version in Fedora is behind latest version of postgresql-jdbc (1200 vs 1207).
We are trying to package latest version into Fedora, but there are dependencies, which are not useless in Fedora (waffle-jna)
Which *are* useless in Fedora. I know that was just an editing mistake. It's a library used in PgJDBC for windows SSPI support.
I don't really see the problem here. If your packaging policy prevents you from incorporating it, patch it out. It's use is simple, self-contained and already optional.
and ones which we are not 100% open source (osgi-enterprise). We talked with upstream quite intensively but not been able to find any solution which would meet our requirements.
... which you should probably outline here, because otherwise nobody will understand the problem.
We think that it's not a good, when open-source project depending on packages, which licence is not 100% clear.
Well, frankly, that's Java. So long as they're soft-dependencies I really don't care.
