Speaking at JBoss World in Berlin yesterday, Marc Fleury, the founder and leader of the JBoss Division of Red Hat, told LinuxWorld that he was pleased that Sun had chosen to release Java under the GPL as “it will extend the life of Java by at least fifteen years.”

From the point of view of the free software movement “it is very good news that Java has been GPL'd, because it creates a protection in terms of intellectual property around the Java Virtual Machine [JVM].”

Fleury believes that JVM will evolve more rapidly under the influence of the open source community, but that Sun will benefit by retaining control of the branding “and that's a good thing” for JBoss, for the developers, and for the open source community. “It's a good thing because we care about the evolution of the platform. We also care about the integrity of the unified virtual machine that has created such a big market for developers who don't have to care about Linux vs. Windows vs. Solaris, and instead talk about a Java platform.”

He sees the GPL's freedom clauses as a mechanism that preserves the intellectual property and integrity of the code. “The GPL is the best of both worlds,“ he said, “because, Stallman's political convictions aside, the GPL creates a very strong notion of intellectual property, and the free software community has been given a superb virtual machine - the Sun implementation - and at the same time, Sun can still monetize their virtual machine with dual licensing.”

Fleury says the lack of a decent open source virtual machine has been “ideologically disturbing. But in practice, nobody cared. Developers have always used the JVM on Linux anyway. It hasn't stopped anybody, but if you take a longer term viewpoint, the release of the Virtual Machine under a GPL license has increased the life of Java by at least 15 years," he said.

The GPL is the right mechanism “because you will see less forks. The branding program will be very stringent. It's a good thing from Sun's standpoint. The GPL allows them to monetize the Java ME environment. There will be a proliferation of the virtual machine, while retaining some monetization for Sun.”

Sun was very open with its partners, “and polled them on how they should open the virtual machine. Our vote, as Red Hat JBoss, was to go GPL. I don't want to take the credit for it, but we're happy to see they're doing the right thing.”
