Issue description
In some conditions, when the driver uses multiple connections to the driver (connection pool), the driver crashes with an OOME. From the attached heapdump, it appears that entries are not released properly in org.jppf.server.queue.JPPFPriorityQueue.sizeMap

I need to check if this happens in the trunk too.
Steps to reproduce this issue
Using the attached code sample and driver and client config files:
  • start one driver and 2 nodes
  • run the client runner application (OOMEJobRunner class)
  • ==> after some time, you get an OOME in the driver
