More about this over at Simon Phipp’s blog Red Hat Joins OpenJDK. If you are not already familiar with the IcedTea effort, take a look at the IcedTea Project Page. IceaTea takes the code from OpenJDK and replaces the encumbered code (binary plugs) with some code from Classpath. I’m assuming that this agreement will make it easier to incorporate some of this code back into OpenJDK project as a replacement for the encumbered code.
(Even though I’ve needled Sun about the continuing Apache dispute, this is, IMO, good news for the OpenJDK effort and for the availability of certified Java on the Linux platform.)
