An outstanding challenge from Leo Simons:
The open source community is giving you a choice: either we all work together, and you release a complete JVM under an open source and/or free software license, or we're going to do things on our own. In the latter case the java community will split and the linux desktop community will fragment further as well. There's a big chance microsoft will win as a result. And like before, you'll have only yourself to blame. In the former case, there's a big chance microsoft will lose, open source will win, and you'll reap the profits.
May the powers be listening.
