> What makes Eclipse Luna in F21 not run on JDK 7 installed manually? > And what can be done to make it work? A quick look at the class files shows that only batik, and sac are targeting 1.8, so if those packages could be rebuilt to target a lesser version it might be possible. Also, org.eclipse.jdt.annotation v2 targets 1.8 but it seems it has a BREE of 1.8 so Matt mentioned it should be disabled. Could a rebuild of batik, and sac be all that's needed ?
