“The OpenJDK project is about 95% of a complete Java implementation. That last 5% or so is what we’ve called ‘encumbrances’, code which we weren’t able to open source.”
It looks like the OpenJDK is really making some good progress. One part of the JDK I’m really happy to see has been open sourced is the crypto library. A few other additions such as the announcement that an open source rasterizer is being looked at to replace the current one in the JDK. I hope to see even more progress in the future.
