title: How to properly set JAVA_HOME in /etc/environment
body: <p>I am trying to add JAVA_HOME system-wide and also add JAVA_HOME/bin to PATH (Ubuntu 12.04). If I add the following 2 lines at the end of /etc/environment, I cannot  login anymore afterwards. If I add the 2 lines to /etc/profile everything works. Wheres the problem?</p>
  
  <pre><code>export JAVA_HOME="/usr/lib/jvm/java-7-oracle"
  export PATH="$PATH:$JAVA_HOME/bin"
  </code></pre>
  
  <p>There is already the following line in /etc/environment (line 1):</p>
  
  <pre><code>PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
  </code></pre>
