Missing support of unshareable JCA connections

We noticed, that JBoss EAP 6.1 handles unshareable resources not conform to the JCA 1.6 specification.

They are used in a shareable way, even when the connections are deployt to be unshareable. Thje resource adapter is deployed without errors and doesn't support shared connections.

Does JBoss EAP 6.1 support unshareable connections at all and if so, how is this configured?

We noticed that this problem orrurs in two configuration:
1. When we use resource annotations
2. Also if we use the old style deployment descriptors.

Resource annotation:

@Resource(description="Resource Referenz to service KDCINF in appication SAMPLE on Windows via UPIC",
name="eis/KDCINF_Sample_Upic",
mappedName="eis/KDCINF_SAMPLE_U",
type=net.fsc.jca.communication.EISUpicConnectionFactory.class,
authenticationType=Resource.AuthenticationType.APPLICATION,
shareable=false)

Deployment descritor:
<resource-ref>
<description>Resource Referenz to service KDCINF in appication SAMPLE on Windows via UPIC</description>
...
<res-type>net.fsc.jca.communication.EISUpicConnectionFactory</res-type>
<res-auth>Application</res-auth>
<res-sharing-scope>Unshareable</res-sharing-scope>
...

Is thera any additional configuration to be done to support unshareable JCA connections?
