47		* <li> All assertions in code running in generated threads must use
48		* the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link

51		* particularly recommended) for other code to use these forms too.
52		* Only the most typically used JUnit assertion methods are defined
53		* this way, but enough to live with.</li>
