It depends on what you mean by "support." If you need support in the normal sense, you should contact Oracle support representatives and ask them. However, given that JDMK is no longer showing up as an Oracle product, I think the answer is likely to be "No."
If you really ask if there is any likelihood of further development of JDMK or OpenJDMK, I would say that it looks rather unlikely 1 . It is best to ask Daniel Fuchs directly ... using the contact information on the openjdmk project website.
