Cannot set primitive value even if type is primitive in SearchArguments

[patduin]

Consider the following failing unit test example for SearchArgumentFactoryTest:

 @Test
  public void primitiveBoolean() throws Exception {
    Fields booleanField = new Fields("A", boolean.class);
    SearchArgumentFactory.Builder.checkValueTypes(booleanField, true);
  }

It will fail because the primitive will be autoboxed in all operator methods of SearchArgumentFactory to an Object. Making the checkValueTypes(...) throw an exception. It works if you use hive's search args directly (probably because it is less strict in the checking).

Same holds for other primitive types.
