Karaf prompt displayed twice
----------------------------

                 Key: KARAF-496
                 URL: https://issues.apache.org/jira/browse/KARAF-496
             Project: Karaf
          Issue Type: Bug
          Components: console
    Affects Versions: 2.2.0, 2.1.4
         Environment: Windows
            Reporter: Jarek Gawor


When running Karaf on Windows with -Djline.terminal=jline.UnsupportedTerminal 
the Karaf prompt in the console is displayed twice after executing some command 
(i.e. pressing enter).

I believe the problem is in the jline library in 
ConsoleReader.readLine(InputStream) as the function will return after seeing 
first \r or \n. But on Windows \r\n is used as the EOL and the function does 
not consume the remaining \n.
