Well, time has come and I must face my responsability on this.
My first important package in Fedora was for OmegaT. AFAIK OmegaT is the best FLOSS computer aid translator tool available. With the time OmegaT has been enjoying a very active development with a significant (to me) handicap: new releases adds new features with new dependencies on java libraries not available in Fedora. As you perfectly know, updating the package requires to add each one of those libraries as new packages. But I can't find the time for such that effort. That's the reason the last Fedora version is 2.6.3 and the lasts at upstream are 3.6.0 / 4.1.2.
So, I give up. I want to retire the package from Fedora because I'm sure I will not be able to update it anymore.
I'll wait some days waiting someone expressing their interest on taking ownership. Otherwise I'll start the retirement process.
PPS: I send an announcement to the Fedora devel mailing list.
