https://docs.jboss.org/hibernate/orm/5.2/javadocs/org/hibernate/query/QueryProducer.html#createNativeQuery-java.lang.String-java.lang.Class-

its written:

 
                                                                <R> NativeQuery<R> createNativeQuery(String sqlString,
                                     Class<R> resultClass)

Create a NativeQuery instance for the given native (SQL) query using implicit mapping to the specified Java type.

Parameters:
    sqlString - Native (SQL) query string
    resultClass - The Java type to map results to
Returns:
    The NativeQuery instance for manipulation and execution
See Also:
    EntityManager.createNativeQuery(String,Class) 
 
                                                            

Have a look at:

resultClass - The Java type to map results to

If you are going to create e.g. a NativeQuery which maps to a Long.class or String.class this does for sure map to a Java type BUT actually looking at the implementation used resultClass is expected to be a Entity class which is known to the persistence unit.

So please correct the javadoc here to something like:

 
                                                                    resultClass - The entity to map results to
