Maty Grosz commented on JCLOUDS-273:
------------------------------------
Sorry, I don't get your point. My code runs across the constructor I described
within the JClouds code itself.
I don't even get to the point I initiate a new Server instance using the
Builder [2].
The exception I get happens during the parse phase of the response to server
api.get(id) call.
In my backend application, I don't set the metadata attribute to anything
(leaving it to be NULL) in the response to the GET call
This is the exception I get on my client side using the JClouds server api:

> URL: https://issues.apache.org/jira/browse/JCLOUDS-273
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-compute
> Reporter: Maty Grosz
>
> Using class org.jclouds.openstack.nova.v2_0.domain.Server – look at the
> constructor “protected Server(… parameters)”:
> OpenStack formal documentation says that the metadata attribute is optional.
> The constructor above calls to(checkNotNull(metadata, "metadata")) – and
> fails.
> No need to check that in this case.
