Red Hat just made it possible to
bootstrap OpenJDK using only Free Software by building on top of gcj and replacing the binary blobs with code from GNU Classpath. The result is called
IcedTea. IKVM also made a
GNU Classpath/OpenJDK hybrid making it possible to run parts of the OpenJDK class libraries on mono and .net. And finally the Cacao team released
a
new version of Cacao that can use either GNU Classpath for a full J2SE implementation or that uses the
Sun GPL J2ME libraries, including jits for lots of different architectures (alpha, arm, mips, ppc, ppc64, x86 and x86_64).

If you read the link, they said that they were going to contribute it to OpenJDK, but they wanted to go ahead and get started instead of waiting for their repositories to be setup. They also said that the code is pretty experimental and wouldn't be ready to check in to the official project anyway.
