This came up when resolving TEIIDDES-2458. The fix attempts to get the correct name in source for the sybase tables, but there's a possibility this will fail. We still want to finish the import, but we'd also like to warn the user the NIS might be incorrect.

<blafond> asmigala: oops. missed it. Since this warning would probably occur on multiple tables/columns it wouldn't be good to pop up a dialog during the processing.
<blafond> asmigala: If we added an IStatus[] to RelationalModelProcessorImpl, we could check it's Severity and throw up a Warning/Error summary dialog after processing?
