If your C++ process starts the Java process, it might benefit from the inheritedChannel. Also, if the Java process is using a file, I recommend exploration of the transferTo and transferFrom methods. When doing file to file IO, these avoid needlessly tripping back and forth between user and kernel space; the same optimizations might kick in if you're using a special socket channel.
