I'm not denying it's been a royal screw up ... particularly with the "sure we're releasing it any day now" message we got for two years. But that is partly due to the fact that the open source guy left the project a while back. > Putting the burden back on you, can you point to a single post about their > project on a community list or name an individual (still employed by Oracle) > that we can discuss with :) ? Um, that question is rhetorical, right? Or are you implying Martin Petersen is no longer at oracle (which will come as news to him, I think)? > We waited years for them to get to the dual license decision in the first place. > > Having looked at their code, I think it is easier to write it - in a community > way - the way we would have it done than to spend another year waiting on their > legal team to change the license. However annoyed we might be with Oracle, reinventing an existing project that already has committed vendor plugin contributors and thus forcing vendors to choose which project to support isn't going to be hugely helpful. Assuming the worst about Oracle, what's the barriers to reusing the plugins (the API is public and doesn't have a licensing issue)? > Clearly, using GPL for a library (not LGPL) is meant to push people into the > commercial license.... You're assuming a malign motive where there could be simple open source ignorance. I'll dig around and see if I can get a read on what they're actually up to.
