120	<	* <li>All assertions in code running in generated threads must use
121	<	* the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link
122	<	* #threadAssertEquals}, or {@link #threadAssertNull}, (not
123	<	* {@code fail}, {@code assertTrue}, etc.) It is OK (but not
124	<	* particularly recommended) for other code to use these forms too.
125	<	* Only the most typically used JUnit assertion methods are defined
126	<	* this way, but enough to live with.
120	>	* <li>All code not running in the main test thread (manually spawned threads
121	>	* or the common fork join pool) must be checked for failure (and completion!).
122	>	* Mechanisms that can be used to ensure this are:
123	>	*   <ol>
124	>	*   <li>Signalling via a synchronizer like AtomicInteger or CountDownLatch
125	>	*    that the task completed normally, which is checked before returning from
126	>	*    the test method in the main thread.
127	>	*   <li>Using the forms {@link #threadFail}, {@link #threadAssertTrue},
128	>	*    or {@link #threadAssertNull}, (not {@code fail}, {@code assertTrue}, etc.)
129	>	*    Only the most typically used JUnit assertion methods are defined

131	>	*   <li>Recording failure explicitly using {@link #threadUnexpectedException}
132	>	*    or {@link #threadRecordFailure}.
133	>	*   <li>Using a wrapper like CheckedRunnable that uses one the mechanisms above.
