org.apache.commons.pool.KeyedObjectPool.borrowObject()
Obtain an instance from my pool for the specified key. By contract, clients MUST return the borrowed object using {@link #returnObject(java.lang.Object,java.lang.Object) returnObject}, or a related method as defined in an implementation or sub-interface, using a key that is equivalent to the one used to borrow the instance in the first place. @param key the key used to obtain the object @return an instance from my pool.
