Could you clarify a bit? Do you mean IPC in a single JVM? (Multiple threads, yes, but at an OS-level only one process.) Or do you mean multiple JVMs? (And truly OS-level inter process communications.)
If it is the first, then maybe something out of java.util.concurrent, like ConcurrentLinkedQueue would do the trick. (I pass message around inbetween my threads with classes from java.util.concurrent with success.)
If the later, then I'm going to just guess and suggest taking a look at RMI, although I don' think it qualifies as fully reliable--you'd have to manage that a bit more 'hands on' like.
