This is probably meaningless for most developers: it is only going to be made available "for use in development, qualification, and testing". Further, there's no information on what license this will be released under.

It's a shame, but given the amount that Azul has poured into research it is not surprising.

At least we can look forward to some interesting benchmarks and code analyses, perhaps?

As for the licensing, did Azul obtain a TCK from Oracle/Sun to say their JVM is for Java? If they did, it is unlikely they will open it up under a permissive license (e.g. MIT, BSD, Apache, etc).

One of Apache Harmony's big reasons for not obtaining and using the Java TCK is that it wouldn't allow them to release their JVM under the Apache license.
