             Summary: Add NPE handling in WSConnectionImpl.invoke
                 Key: TEIID-3383
                 URL: https://issues.jboss.org/browse/TEIID-3383
             Project: Teiid
          Issue Type: Bug
          Components: Connector API
    Affects Versions: 8.4.1
            Reporter: Bas Piepers
            Assignee: Steven Hawkins
            Priority: Minor


In the WSConnectionImpl.java class in the org.teiid.resource.adapter.ws package (of connector-ws-8.4.1-redhat-9.jar) in the invoke(DataSource ds) method at the end it tries to get the content-type from the response in line 164 and then returns the first item in the list of content types:

ArrayList contentTypes = (ArrayList)this.responseContext.get("content-type"); //$NON-NLS-1$
return new HttpDataSource(url, (InputStream)response.getEntity(), (String)contentTypes.get(0));

However if the web service that it calls returns an error code (like 415, for example) it does not contain a content-type in its header. Basically this method expects a result to be returned all the time with a corresponding content-type which is not right. The line where it calls contentTypes.get(0) may result in a NPE.
