  // This is a regression test for dartbug.com/14442.
  //
  // If you have a long chain of path dependencies with long relative paths,
  // you can end up with a combined path that is longer than the OS can handle.
  // For example, the path that revealed this bug was:
  //
  // C:\jenkins-slave\workspace\mSEE-Dev\ozone\dart\portfolio-manager\src\main\
  // portfolio-manager\..\..\..\..\portfolio-common\src\main\portfolio-common\
  // ../../../../dart-visualization/src/main/dart-visualization\lib\src\vega\
  // data\transform\visual
  //
  // This test ensures that we're normalizing at some point before we throw the
  // path at the OS to choke on.
