> PropertyQuery should offer the method getSingleResult() for the same reason it exists in the JPA Query interface: to fetch a single result but also assert that there is only one result to be fetched. If more than one property is matched when getSingleResult() is called, an exception will result. 
> Using getFirstResult() to return exactly one result is inappropriate (and could lead to bugs) because it could hide the fact that multiple properties are being inadvertently matched. As a workaround, the developer would currently have to run getResultList() to ensure only one property matches. Offering a getSingleResult() would resolve these issues.
