It's true that the Linux kernel is developed in a distributed
tree-of-trees model, just like OpenJDK, and Linus himself
is the most outspoken advocate of distributed source code
control systems.  (I mostly agree with him there)

One difference is the culture of testing.  The Linux kernel
is hard to test, and doesn't seem to have a strong culture
of testing, while the JDK has on the order of a million tests
available to be run, which makes great stability and reliability
