WSDL and java.lang.NullPointerException

I have a fairly simple component that has been in a production environment,
in ColdFusion 9, for the past year. We have recently upgraded to Lucee,
and find that the invocation of the component with the WSDL parameter
triggers a java.lang.NullPointerException error.

Suggestions?

An update… I created a static wsdl, added the wsdlfile attribute to the
cfcomponent tag, and the wsdl now appears. Seems the ability to generate
the wsdl on the fly is missing.
