If we take Scala for example that's only true if you write Java-like Scala code and what's the point of that? Once you go deep with Scala magic it goes downhill, but prob. 80% as fast. I think Java and other JVM languages can co-exist nicely, depending on the task at hand, there is no "need" to kill anything, I wish you could mix and match code from different JVM languages easily.
