So the basic JBDS installer is 70MB fatter. From my understanding it's because we now ship a huge forge2 runtime (50MB), Tern, the JVM Monitor and probably some other minor stuff.

Fair enough. But do we really need to add all the source features/plugins to the installer? If we're legally bound to provide sources for JBoss plugins, couldn't we provide them via an other way? (p2 only).

I reckon we could save ~37 MB by not shipping sources in the installer. I know storage is cheap and d/l speeds are faster but that's not an excuse.
