KeyedObjectPool
borrowObject
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 Object in the first place.
This method should be used when an object that has been borrowed
is determined (due to an exception or other problem) to be invalid.
If the connection should be validated before or after borrowing,
then the PoolableObjectFactory.validateObject(java.lang.Object)
method should be
used instead.

obj

instance to be returned.
