Releases the passed {@link StatefulSessionComponentInstance} i.e. marks it as no longer in use. After releasing the
instance, this method releases the lock, held by this thread, on the stateful component instance.

@param instance The stateful component instance
@param toDiscard indicates if bean should be discarded due to exception
Releases the passed { @link StatefulSessionComponentInstance } i . e . marks it as no longer in use . After releasing the instance this method releases the lock held by this thread on the stateful component instance .
