public static void initialize(){
  /*
    Since trying Java 8, started to get weird behavior on a Linux cluster.
    Issue raises from GUI now trying to write on disk (ie due to Fonts...).
    However, that sometimes strangely fails, even though executed before any
    sandbox. It happens quite often on cluster experiments, but was not able
    to reproduce it to debug :(
    As workaround, we try here to load default file system (it would happen anyway when
    loading fonts in Java 8), but do not crash the test suite (ie throw exception here
    in this method, which is usually called from a @BeforeClass). Reason is that
    maybe not all tests will access GUI.
   */
  try{
    FileSystems.getDefault();
  } catch(Throwable t){
    logger.error("Failed to load default file system: "+t.getMessage());
    return;
  }
  /*
   * Force the loading of fonts.
   * This is needed because font loading in the JVM can take several seconds (done only once),
   * and that can mess up the JUnit test execution timeouts...   
   */
  (new javax.swing.JButton()).getFontMetrics(new java.awt.Font(null));
