Description Rüdiger Herrmann

An 'empty' entry point like the one below, causes a NullPointerException when it is used.

class MyEntryPoint implements IEntryPoint {
  public int createUI() {
    return 0;
  }
}

Render#execute() was changed to do nothing if no display is present. 
Changes are in CVS HEAD.
