<DD>A container invokes this method before it removes the EJB object
 that is currently associated with the instance. This method
 is invoked when a client invokes a remove operation on the
 enterprise Bean's home interface or the EJB object's remote interface.
 This method transitions the instance from the ready state to the pool 
 of available instances.
 
 <p> This method is called in the transaction context of the remove 
 operation.
