Is there a list of JEPs which includes the affiliation of the person proposing them? It would be interesting to see how many get approved. I would expect it's a lot easier to make progress from 'inside the tent' i.e. an employee of Oracle, Red Hat etc.
Having said that, from the link posted by carimura [0] it looks like the author of this one is doing an excellent job of engaging with Brian Goetz and others at oracle.
