Getter of BA object fails to construct class instance

Deserialization fails with following exception:

Caused by: java.lang.IllegalArgumentException: Failed to construct instance of class org.opendaylight.yang.gen.v1.urn.ieee.params.xml.ns.yang.dot1q.types.rev150626.dot1q.tag.or.any.Dot1qTag$VlanId for input 2420

when I do

dot1qTag.getVlanId()

here is yang model:
https://git.fd.io/hc2vpp/tree/v3po/api/src/main/yang/dot1q-types.yang

after debugging, I found that

EncapsulatedValueCodec.deserialize()

fails because of

java.lang.ClassCastException: Cannot cast java.lang.String to java.lang.Integer

In case if I use analogous restconf request, DataObject is retrieved from cache
at LazyDataObject.getBindingData and deserialization is not invoked.

The same request works if we downgrade odl dependencies to Beryllium-SR2.

I noticed that in case of beryllium, the generated Dot1qTagVlanIdBuilder was invoked.
