             Summary: ModelHandler won't accept a file name without a directory component
                 Key: CALCITE-1360
                 URL: https://issues.apache.org/jira/browse/CALCITE-1360
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.8.0
            Reporter: Aaron Dossett
            Assignee: Julian Hyde
            Priority: Trivial


A model referencing file with no directory component throws an NPE. In the example below replacing {code}foo.json{code} with {code}./foo.json{code} resolves the problem.
