"We are basing ourselves now on OpenJDK and to do that we have to release our stuff as open source as well because it’s substantially derived work off at the Open JDK. So the managed runtime is essentially a source drop as of a couple of months ago, and we are due to put on another source drop before long here. Essentially what it is I am building and running on my desk every day. Zing is the productized version of that that we intend to sell for money. There are a few features we don’t have to put out in the public domain, and those are going to be extras, are going to be probably the high res profiling tools."
