code generator should not generate this.value = null

org.opendaylight.yang.gen.v1.urn.ietf.params.xml.ns.yang.ietf.inet.types.rev100924.IpAddress

public IpAddress(Ipv4Address _ipv4Address)

{ super(); this._ipv4Address = _ipv4Address; this._ipv6Address = null; this._value = null; }

This constructor is possibly wrong because it returns null on getValue(). If the instance is created using this constructor it cannot be sent over JMX.

Consider this example:
client.setAddress(new IpAddress(new Ipv4Address("127.0.0.1")));
will fail
client.setAddress(new IpAddress("127.0.0.1".toCharArray()));
will succeed (value != null)

Proposed fix: _value should be filled using _ipv4Address.getValue()

Detail:

The failure looks like this:
