Important migration to JZMQ 2.1.2 and ZMQ 3.X.
Support of JAVA 1.7 for ROQ.
Main migration to ZMQ 3.x
1) the ZMQ.poller was deprecated
2) the poller timer is now in millisecond and not in microsecond as in ZMQ 2.X
Bug corrections found with new JZMQ 2.1
Out sourced this test in its own test case. That was easier for locating race conditions in tests.
Update change for requirements ZMQ and JZMQ, and the release name.
