Re-sizeable Java BlockingQueue

So I am using a fixed sized BlockingQueue [ArrayBlockingQueue] in a producer/consumer type application, but I want the user to be able to change the queue size on the fly. Problem is there is not a BlockingQueue implementation that allows changing capacity after creation. Anyone ever come across this before? Any ideas?

The most obvious solution (may or may not be appropriate depending on your circumstances) would be to simply instantiate a new queue with the updated capacity you want. Then push everything from the old queue into the new queue.

You could extend LinkedBlockingQueue. Its limit is is a soft limit (i.e. just an additional check) and you could make this something you can change (by disabling the built in one and putting in your own)
