com.sun.ejb.containers.util.pool.NonBlockingPool

NonBlockingPool pool provides the basic implementation of an object pool. The implementation uses a linked list to maintain a list of (available) objects. If the pool is empty it simply creates one using the ObjectFactory instance. Subclasses can change this behaviour by overriding getObject(...) and returnObject(....) methods. This class provides basic support for synchronization, event notification, pool shutdown and pool object recycling. It also does some very basic bookkeeping like the number of objects created, number of threads waiting for object.
Subclasses can make use of these book-keeping data to provide complex pooling mechanism like LRU / MRU / Random. Also, note that AbstractPool does not have a notion of pool limit. It is upto to the derived classes to implement these features.
