From Java IO: Pipes

Pipes in Java IO provides the ability for two threads running in the same JVM to communicate. Therefore pipes can also be sources or destinations of data.

You cannot use a pipe to communicate with a thread in a different JVM (different process). The pipe concept in Java is different from the pipe concept in Unix / Linux, where two processes running in different address spaces can communicate via a pipe. In Java, the communicating parties must be running in the same process, and should be different threads.

Are you sure it is possible? Are there any examples where jvm communicates with other runtimes through these pipes?
