j.u.c provides a toolkit for a wide range of uses - some things higher-level
than others, but ultimately it comes down to application needs: you use the
tools that do the job best.
I still can't quite grasp exactly what you need, but based on the statement
above would it suffice to simply have your readers increment an
AtomicInteger before taking from the queue and decrement it after - the
count then tracks very approximately how many reads are in progress?
