Adding an experimenter OXM Id using setOxmIds(List<U32>)

[SADIQIoT]

Hi,
I am trying to add an experimenter field in the OFTableFeature message using the property OFTableFeaturePropMatch. The setOxmIds(List<U32>) method can only take a list of U32's which is the length of a basic oxm field header. However, the experimenter field header is 64bits, so it cannot be added using this method.
Can you lead me to how to overload the setOxmIds to take a generic list (which can accept both U32 and U64 )? Or any other workaround you can think of.

Thanks,
Enas
