Try removing fields that have a 'null' value, example:

"qos_policy_id": null,

When I remove those fields, everything works fine.

Please also note, qos_policy_id isn't even a supported field, but apparently
a value 'null' is confusing JAXB in some way.

This should fix the NPE:

You hit MOXy bug.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=475475
networking-odl has already the bug workaround.
https://review.openstack.org/#/c/281621/

I uploaded a new patch to add qos_policy_id to its bug workaround at
https://review.openstack.org/#/c/329596/

If it works for you, I'll merge the patch for networking-odl.

I merged tha patch https://review.openstack.org/#/c/329596/ into networking-odl.
Can you please test it?
