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	+	*
67	+	* <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>
85	+	*
86	+	* </ul>
