DDL importer problems - TeiidServerManager initialization problem

When Importing from DDL to create a new view model (DDL File >> Source or View model), the following problems appear:

a) when choosing auto-select for dialect, the wizard raises the difference panel after hitting Next with generic "Error encountered importing DDL" message and a "No difference report was found" message.

b) when leaving auto-select unchecked for dialect, clicking Next produces a DDL failed to parse error (as well as a 'No difference report was found" error.

The DDL in question works in JBDS 6 and earlier.

Version-Release number of selected component (if applicable):
JBDS 7 with JBDSIS 7 beta 4

How reproducible:
Consistent.

Steps to Reproduce:
Import attached DDL via importer.
