Deprecated.

DefaultComponentPool is no longer used by the PoolableComponentHandler.

public class DefaultComponentPool
extends org.apache.avalon.excalibur.pool.SoftResourceLimitingPool
implements org.apache.avalon.framework.activity.Initializable

This is the implementation of Pool for Avalon Components that is thread safe. For Component Management, we need soft resource limiting due to the possibility of spikes in demand. This pool will destroy all unnecessary Components when they are no longer needed.
