Validation issue (NPE) while importing WSDL in the Teiid Designer

Issue

• I'm getting following validation error while importing attached WSDL file using "WSDL File or URL >> Web Service Model" wizard:

"WS-I: A problem occured while running the WS-I WSDL conformance check: 
 org.eclipse.wst.wsi.internal.analyzer.WSIAnalyzerException: null"

• When I ignore the NPE and click Next to complete the wizard, it errors on creating the Web Service Model
