Can not parse 2 complex attributes with same XML element name in 2 different attribute groups

This issue is a followup on WFLY-8021 where there was 2 complex attributes on the same resource:

• target-credential-reference (attribute group = target, xml element name = credential-reference)
• source-credential-reference (attribute group = source, xml element name = credential-reference)

with the corresponding XML structure:

<jms-bridge name="myBridge" ...>
   <source ...>
        <credential-reference clear-text="passwordOut!"/>
   </source>
   <target ...>
        <credential-reference clear-text="passwordOut!"/>
   </target>
</jms-bridge>

The parser fails to parse the source-credential-reference as the persistent XML description elementsAttribute map has a single entry for the credential-reference key that point to the target-credential-reference attribute.
