31 * Simple class to load resources using the 1.2
32 * security model. Since the html support is loaded
33 * lazily, it's resources are potentially fetched with
34 * applet code in the call stack. By providing this
35 * functionality in a class that is only built on 1.2,
36 * reflection can be used from the code that is also
37 * built on 1.1 to call this functionality (and avoid
38 * the evils of preprocessing). This functionality
39 * is called from ParserDelegator.getResourceAsStream.
