[zcervink]

• issue appears on unpredictable places in the middle of the run of a JUnit test

• issue associated with the waitFor() function from the Remote-Robot framework in which the issue appears

• issue seen many times on OS X and Windows, never on Linux

• ROOT CAUSE: it is not clear where exactly the issue appear on deeper level

• WORKAROUND: rerun the tests

• error description:

  java.net.ConnectException: Failed to connect to /127.0.0.1:8580
     ...
  Caused by: java.net.ConnectException: Connection refused: connect
     ...
