Unexpected error occurred when rebuilding virtual database

Issue

• We are migrating from EDS 5.3.1 to JBoss Data Virtualization 6.0.
  When trying to rebuild the Virtual Database, an unexpected error was thrown for each 'source' that was defined in the project:
  An unexpected error occurred running the Create Workspace Preview VDB for "/eds/sources/ZoneSoap.xmi" job.

org.eclipse.core.runtime.CoreException: An error creating the Preview VDB for model "/eds/sources/ZoneSoap.xmi" occurred.

• Manually setting the translator name (right-click on source and select Modeling -> Set Translator Name) doesn't always appear to correct the issue, but ensuring that the VDB contains a valid Translator Name for each SOAP view seems to work.
