I had a Viatra query project with Java 7 and the compiler generates
rawStreamAllValuesOf methods in the following way:

protected Stream<SomeType> rawStreamAllValuesOfsomeType(final Object[] parameters) {\
  return rawStreamAllValues(POSITION_SOMETYPE, parameters).map(SomeType.class::cast);\
}\

with this error for the SomeType.class::cast part:
Method references are allowed only at source level 1.8 or above
