code: public static void printError (String message, Throwable throwable, boolean force) {
  		if (isDebugEnabled () || force) {
  			StringBuilder outputBuilder = new StringBuilder ();
  			outputBuilder.append (message).append ("\nThrowable:\n");
  			outputBuilder.append (DefaultFormatter.getFullThrowableMsg (throwable));

docs: Print a message to <code>System.err</code>, with an every-line prefix: "log-helper ERROR: ", and specifying a full stack trace of a {@link java.lang.Throwable Throwable}
  @param message
  @param throwable
  @param force <code>true</code> if we need to override the debug enabled flag (i.e. the message is REALLY important), <code>false</code> otherwise
