I got this NPE too, but seems at different place:

ponseRendererImpl.java:79)
On the html page, the Ajax error shows:
Ajax failure: Status 500 for
/sql-library/delimitedtextviewer.loop.rowinjector:inject/1235082471277?t:formcomponentid=DelimitedTextViewer:form&t:formid=form:
java.lang.NullPointerExceptionCommunication with the server failed:
java.lang.NullPointerException
It's seems related to xml namespace, after I removed doctype and
remove xmlns in <html> tag, the error disappeared, however, some
other components look weird.
Any ideas about it?
Thanks,
Yunhua
