title: Karaf with UTF-8
body: <p>If I start Karaf (2.3.4) and the following environment is set</p>
  
  <pre><code>JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8
  </code></pre>
  
  <p>It is not possible, anymore to use the up and down arrow to get the last command (in the karaf command line), is this a bug I should report or isn't it allowed to use this option with karaf?</p>
