We are a bit loose here with terms "free" and "commercial". The oracle JVM is open source, it is free to use and the trademark is owned by a company. That is not much different then using a tool for cassandra like a driver hosted on github but made my a company. The thing about a JVM is that like a kernel you want really smart dedicated people working on it. Oracle has moved the JVM forward since taking over sun. You can not just manage a JVM like say the freebsd port of x maintained by 3 part time dudes that all get paid to do something else.
