MeetingDetectorTAE's subcomponent TutorialDateTime shows a warning in its process method when deployed with FileSystemCollectionReader :
No output is being produced by the TutorialDateTime annotator because the Result
Specification did not contain a request for the type
org.apache.uima.tutorial.DateAnnot with the language 'x-unspecified'
(Note: this message will only be shown once.)
This is due to the fact that the CAS language is not specified. Modify CollectionReader's descriptor to set Language parameter
