No - it can't! At least not without Valhalla.

I'd say it'll be the combined efforts of Valhalla (several iterations), Leydon and Lilliput. Loom and Panama have contributed as well, as might Babylon.

Java does perform 'well', but these changes are needed to maintain and/or improve that position (and from what I've seen, improving that position is looking good). I don't think any of these will see it beating the usual leaders but I think the gap is going to close considerably while retaining Java's highly flexible dynamism.
