--------------------------------------

             Summary: CLI trainers and cross eval should print an error if 
training data is insufficient
                 Key: OPENNLP-937
                 URL: https://issues.apache.org/jira/browse/OPENNLP-937
             Project: OpenNLP
          Issue Type: Bug
          Components: Command Line Interface
            Reporter: Joern Kottmann
            Priority: Minor
             Fix For: 1.7.1


Currently the InsufficientTrainingDataException stack trace is printed to the 
console. We should catch this exception and provide the user with some help to 
deal with this problem.

We get often questions about this on the ml and a helpful error could probably 
answer it without having people (the few who bother) ask for help.
