> In the method 'clearOldest' of GenericKeyedObjectPool the class 
> ObjectTimestampPair is used as keys for a TreeMap wich compares the elements 
> by System.currentTimeMillis().
> If two ObjectTimestampPair  instances have the same timestamp the value in 
> the map will be overridden and the wrong instance will be destroyed.
> If you use the pool with hibernate it will be result in a Statement already 
> close Exception. 
> As a patch i return never zero in the compareTo method of ObjectTimestampPair.
