Thanks for your reminding about the maintenance, code and legal issues
about the MIPS porting. We know that it will take a very long time
and hard efforts to make these changes to be merged into the OpenJDK
mainline. We will do everything we can do to make that happen. Just tell
us if we could do anything.

That sounds interesting. Could we access the Reservoir tree from the
