Thanks for answering.
Yes, I can download the JDV 6.2 from the link provided. But it need EAP 6.4.3 and can't be installed in EAP 6.4, or did I miss something?
I believe 6.4 upgrade is done as patch release, so that is only available for Red Hat customers. Patches are not available for community users, however all the patches are committed also upstream albeit may not be in the same version of Teiid as they do in JDV.
