Then you must use the Sun (or IBM or BEA) VM. gcj in rawhide has just recently merged in the 1.5 branch of GNU Classpath so you can expect that in Fedora 7. > But what you're saying here, if I get you right, is that if I need > Java 1.5, there wouldn't be any advantage in using Fedora Eclipse over > the upstream version, but if the Fedora Java stack suffices for the > plugins, Eclipse itself would run faster, although the plugins won't > benefit. Confused again? :-) I don't think it's worth talking about absolute performance of gcj-compiled binaries vs. the Sun JIT 'cause there are a lot of factors and it's difficult to get hard numbers that apply in all cases. As for using Fedora Eclipse over an upstream download, it's up to you. We include a few patches. These have either been applied upstream after the release we're shipping or are useful for multi-user, RPM-based installations. There's also the benefit of having it installed and managed by yum and the whole RPM infrastructure but I figure that goes without saying :) Andrew
