Hi,

Could you please provide me with a test case that throws the expected NPE?

So far I haven't managed to reproduce the issue : I've attached a test case with a simple query containing a lower(...) which seems to work as expected (tested against hibernate/master).

In QueryImpl#extractParameterInfo, QueryImpl#mightNeedRedefinition is only called for named parameters. Ordinal parameters should work correctly. As for the named parameters, in the case of my simple query, the following line returns null :

Class javaType = namedParameterTypeRedefinition.get( name );

As a result, the following if is not executed and no exceptions are raised.

Thank you
