Introduction of 1.7 is the first such case where this may hold true. And even then, we would like the overlap to be as little as possible and switch over to Java 7 completely. Frankly, there is little if any need for alternatives for java in Fedora given that there is only OpenJDK. However we keep it in case users want to install 3rd party JDKs/JREs via the jpackage-wrapper RPM. > > > Are there any major objections to the above? > > > Yeah, I'm with Peter Robinson that this change is coming too late in the > cycle.

Since it is just to test if Java 7 can build it, I was going to install all BRs of packages that need java to build, and then just build them one after another. It might be faster this way than doing individual builds given the # of packages. I will let you know if anything changes and I do need the tag though. Thanks for the offer!
