MTJ depends on netlib-java, which is technically a translation of the

If they really are BSD, then there should be no problem.  BSD allows
redistribution with attribution, preservation of the copyright notice and no
implication of endorsement.

There is a big issue with dependencies, but a much smaller issue with major
source code contributions.  Essentially what I mean by "adopting wholesale"
would be for commons math to ingest MTJ.  IN the best world, the contributor
communities would merge as well.  There would still be plenty of issues such
as the conditional dependency on native libraries.  I am not sure how that
should play out.
