Re: intended use

java.util.concurrent.Semaphore only works in the same JVM.  If you have two
Java programs running in different processes, then java.util.concurrent will
not work, CLIPC will.

What's more, if you are trying to synchronize Java and non-Java processes,
CLIPC semaphores will work, whereas java.util.concurrent will not.

The basic goals of CLIPC are 1) provide synchronization primitives that simply
do not exist in the JRE such as inter-process semaphores and FIFOs; and 2)
simplify the primitives that do exist such as shared memory.
