Issue description
The goal is to make the JMX generic/JMXMP connector available via NIO (socket channels) rather than straight Sockets on the server side.

One of the main benefits is that it will allow us to use a shared thread poool for all JMX client connections. This should result in a much reduced number of threads running in the driver, due to its JMX connections to all the nodes: instead of 2 threads per node, there would be at most the number of threads in the pool.

Along with scalability and performance improvements, this will allow us to get rid of the separate management port used in the JPPF configuration, since it will use the same port as the other services (e.g. the default 11111 port).

I currently have a first implementation that is integrated with JPPF management. It seems to keep its promises, up to a certain point: number of JMX threads is kept low and the JMX server can use the same port as the JPPF driver.

There are still many things to do:
  • iron out the bugs: possible connection leaks, incomplete exception handling, possible deadlocks
  • implement automated tests providing sufficient coverage
  • test with TLS connections
  • perform scalability tests, stress tests, endurance tests
  • integrate in the build process (both standalone and integrated in JPPF components)
  • document the connector
