    [ https://issues.jboss.org/browse/TEIID-4617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13334847#comment-13334847 ] 

Steven Hawkins commented on TEIID-4617:
---------------------------------------

> I do not think Teiid explicitly sets any TCCL in JCA layer

No, I'm saying that should be the responsibility of the JCA layer.

> however stack shows that the TCCL is Teiid's translator module, so some where in JCA layer this is being set up

No, Teiid does explicitly set the tccl for calls into the translator layer.

> Workaround to try is to setup "org.mondrian" as dependency on olap translator module.

Yes, Jan has confirmed that works, but that is not a real solution.

> But the class is present in the new version of Mondrian too, see attached screenshot with decompiled jar structure.
> One workaround I found was to add dependency into olap translator's module.xml pointing at the org.mondrian module, which contains the mondrian jar.
> But this action is not required when using Mondrian 3.5.0.
