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

             Summary: VMF fails to run tests on MS-Windows
                 Key: DAFFODIL-2007
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2007
             Project: Daffodil
          Issue Type: Bug
          Components: Windows
    Affects Versions: 2.2.0
            Reporter: Michael Beckerle



Users trying to test VMF on windows report that 'sbt test' works fine on mil-std-2045, but fails for VMF.

Some debugging shows that when the DaffodilConstructingLoader creates a scala.io.Source from the URI, the resulting source faults on the first hasNext call.

I added some instrumentation to DaffodilConstructingLoader.scala:

{{class DaffodilConstructingLoader(uri: URI, errorHandler: org.xml.sax.ErrorHandler)
  extends ConstructingParser({
    //
    // Note: we must open the XML carefully since it might be in some non
    // default encoding (we have tests that have UTF-16 for example)
    //
    val is = uri.toURL.openStream()

    System.err.println("URI to open: " + uri)

    val rdr = new XmlStreamReader(is) // apache has a good thing for determining XML charset
    val csName = rdr.getEncoding

    System.err.println("Charset is: " + csName)

    import collection.JavaConverters._
    val lines = IOUtils.readLines(rdr).asScala
    System.err.println("First line is " + lines.headOption.getOrElse("Nothing."))

    rdr.close()
    val source = Source.fromURL(uri.toURL, csName) // tbd: can one create a Source somehow directly from the rdr?

    val hn = source.hasNext
    System.err.println("First hasNext call succeeded with result: " + hn)

    source
  }, true) {}}

The resulting print out for running the single test TestVMFFullMessages.test_K00_1 is below. It never gets to the last println in the above code. It fails on the hasNext call on the Source. Prior print statements show the file can be opened and accessed, so it's something to do with the scala.io.Source, and creating one from a URL that is the problem it seems.

Here's the error:

{{URI to open: file:/E:/dataiti/git/fouo-schemas/vmf/schema/target/classes/com/tresys/mil-std-6017/xsd/vmf.main.gen.dfdl.xsd
