Issue description
This is a regression from the Enhancement JPPF-183 - Add relevant classes cache lookups in the driver. When multiples nodes send compute() requestss concurrently, it can happen that only one request out of sevral is sent to the client for execution. This causes for the other requests to have the JPPFCallable returned instead of a computation result, which causes the ClassCastException in the node.
Steps to reproduce this issue
This can be reproduced with a single node where multiple tasks call compute() concurrently
