/**
 * Base class for JSR166 Junit TCK tests.  Defines some constants,
 * utility methods and classes, as well as a simple framework for
 * helping to make sure that assertions failing in generated threads
 * cause the associated test that generated them to itself fail (which
 * JUnit does not otherwise arrange).  The rules for creating such
 * tests are:
 *
 * <ol>
 *
 * <li> All assertions in code running in generated threads must use
 * the forms {@link #threadFail}, {@link #threadAssertTrue}, {@link
 * #threadAssertEquals}, or {@link #threadAssertNull}, (not
 * <tt>fail</tt>, <tt>assertTrue</tt>, etc.) It is OK (but not
 * particularly recommended) for other code to use these forms too.
 * Only the most typically used JUnit assertion methods are defined
 * this way, but enough to live with.</li>
 *
 * <li> If you override {@link #setUp} or {@link #tearDown}, make sure
 * to invoke <tt>super.setUp</tt> and <tt>super.tearDown</tt> within
 * them. These methods are used to clear and check for thread
 * assertion failures.</li>
 *
 * <li>All delays and timeouts must use one of the constants <tt>
 * SHORT_DELAY_MS</tt>, <tt> SMALL_DELAY_MS</tt>, <tt> MEDIUM_DELAY_MS</tt>,
 * <tt> LONG_DELAY_MS</tt>. The idea here is that a SHORT is always
 * discriminable from zero time, and always allows enough time for the
 * small amounts of computation (creating a thread, calling a few
 * methods, etc) needed to reach a timeout point. Similarly, a SMALL
 * is always discriminable as larger than SHORT and smaller than
 * MEDIUM.  And so on. These constants are set to conservative values,
 * but even so, if there is ever any doubt, they can all be increased
 * in one spot to rerun tests on slower platforms.</li>
 *
 * <li> All threads generated must be joined inside each test case
 * method (or <tt>fail</tt> to do so) before returning from the
 * method. The <tt> joinPool</tt> method can be used to do this when
 * using Executors.</li>
 *
 * </ol>
 *
 * <p> <b>Other notes</b>
 * <ul>
 *
 * <li> Usually, there is one testcase method per JSR166 method
 * covering "normal" operation, and then as many exception-testing
 * methods as there are exceptions the method can throw. Sometimes
 * there are multiple tests per JSR166 method when the different
 * "normal" behaviors differ significantly. And sometimes testcases
 * cover multiple methods when they cannot be tested in
 * isolation.</li>
 *
 * <li> The documentation style for testcases is to provide as javadoc
 * a simple sentence or two describing the property that the testcase
 * method purports to test. The javadocs do not say anything about how
 * the property is tested. To find out, read the code.</li>
 *
 * <li> These tests are "conformance tests", and do not attempt to
 * test throughput, latency, scalability or other performance factors
 * (see the separate "jtreg" tests for a set intended to check these
 * for the most central aspects of functionality.) So, most tests use
 * the smallest sensible numbers of threads, collection sizes, etc
 * needed to check basic conformance.</li>
 *
 * <li>The test classes currently do not declare inclusion in
 * any particular package to simplify things for people integrating
 * them in TCK test suites.</li>
 *
 * <li> As a convenience, the <tt>main</tt> of this class (JSR166TestCase)
 * runs all JSR166 unit tests.</li>
 *
 * </ul>

28	dl	1.1	* <tt>fail</tt>, <tt>assertTrue</tt>, etc.) It is OK (but not
29			* particularly recommended) for other code to use these forms too.
30			* Only the most typically used JUnit assertion methods are defined

34	dl	1.1	* to invoke <tt>super.setUp</tt> and <tt>super.tearDown</tt> within

36			* assertion failures.</li>

38	dl	1.6	* <li>All delays and timeouts must use one of the constants <tt>
39			* SHORT_DELAY_MS</tt>, <tt> SMALL_DELAY_MS</tt>, <tt> MEDIUM_DELAY_MS</tt>,
40			* <tt> LONG_DELAY_MS</tt>. The idea here is that a SHORT is always
41	dl	1.5	* discriminable from zero time, and always allows enough time for the
42			* small amounts of computation (creating a thread, calling a few
43	dl	1.1	* methods, etc) needed to reach a timeout point. Similarly, a SMALL
44			* is always discriminable as larger than SHORT and smaller than
45			* MEDIUM. And so on. These constants are set to conservative values,
46	dl	1.2	* but even so, if there is ever any doubt, they can all be increased
47	jsr166	1.27	* in one spot to rerun tests on slower platforms.</li>
48	dl	1.1	*
49			* <li> All threads generated must be joined inside each test case
50			* method (or <tt>fail</tt> to do so) before returning from the
51	dl	1.6	* method. The <tt> joinPool</tt> method can be used to do this when
52	dl	1.1	* using Executors.</li>

56			* <p> <b>Other notes</b>
57			* <ul>
58			*
59			* <li> Usually, there is one testcase method per JSR166 method
60			* covering "normal" operation, and then as many exception-testing
61			* methods as there are exceptions the method can throw. Sometimes
62			* there are multiple tests per JSR166 method when the different
63			* "normal" behaviors differ significantly. And sometimes testcases
64			* cover multiple methods when they cannot be tested in
65			* isolation.</li>
66	jsr166	1.27	*
67	dl	1.6	* <li> The documentation style for testcases is to provide as javadoc
68			* a simple sentence or two describing the property that the testcase
69			* method purports to test. The javadocs do not say anything about how
70			* the property is tested. To find out, read the code.</li>
71			*
72			* <li> These tests are "conformance tests", and do not attempt to
73			* test throughput, latency, scalability or other performance factors
74			* (see the separate "jtreg" tests for a set intended to check these
75			* for the most central aspects of functionality.) So, most tests use
76			* the smallest sensible numbers of threads, collection sizes, etc
77			* needed to check basic conformance.</li>
78			*
79			* <li>The test classes currently do not declare inclusion in
80			* any particular package to simplify things for people integrating
81			* them in TCK test suites.</li>
82			*
83			* <li> As a convenience, the <tt>main</tt> of this class (JSR166TestCase)
84			* runs all JSR166 unit tests.</li>
