PoolUtils.erodingPool

Returns a pool that adaptively decreases its size when idle objects are no longer needed. This is intended as an always thread-safe alternative to using an idle object evictor provided by many pool implementations. This is also an effective way to shrink FIFO ordered pools that experience load spikes.

@param pool the ObjectPool to be decorated so it shrinks its idle count when possible. @param <T> the type of objects in the pool @return a pool that adaptively decreases its size when idle objects are no longer needed. @see #erodingPool(ObjectPool, float)
