Preview Data on certain models causes JBDS to go into unrecoverable loop

When using the FinancialsDemo, our internal demo project (https://docspace.corp.redhat.com/docs/DOC-56653), previewing data from the CustomerHoldings/BrokerageModel (models AccountHoldings, AccountValue, and HighNetWorthCustomers) causes JBDS/Teiid to go into an unrecoverable loop where you must abruptly "force quit" the IDE to regain control. I have also seen this behavior when attempting to preview data from one of the included Web Services in the project.

The following snippet is repeated multiple times in the EDS server log at the time that the process seems to get stuck in a loop:
