ClassCastException in EnumByNameType When Setting To Null

[ssaarela]

SQLUpdate update =...;

update.set(qType.enumValue, null);

=>

Caused by: java.lang.ClassCastException: com.mysema.query.sql.types.Null cannot be cast to java.lang.Enum
at com.mysema.query.sql.types.EnumByNameType.setValue(EnumByNameType.java:26) ~[querydsl-sql-2.9.0.jar:na]

The problem is that Configuration.getType > JavaTypeMapping.getType > typeByColumn returns EnumByValueType instead of UntypedNullType (or NullType - what's the difference?) which is returned in case of e.g. StringPath. Null expression should override typed access.

UntypedNullType is used for cases where parameter metadata is not available. It's used internally in Querydsl SQL for CUBRID, MySQL and Oracle.
