+     * As of release 7, the platform supports the notion of
+     * <i>suppressed exceptions</i> (in conjunction with automatic
+     * resource management blocks). Any exceptions that were
+     * suppressed in order to deliver an exception are printed out
+     * beneath the stack trace.  The format of this information
+     * depends on the implementation, but the following example may be
+     * regarded as typical:
+     *
+     * <pre>
+     * Exception in thread "main" java.lang.Exception: Something happened
+     *  at Foo.bar(Foo.java:10)
+     *  at Foo.main(Foo.java:5)

+     *          at Foo.bar(Foo.java:9)
+     *          ... 1 more
+     * </pre>
+     * Note that the "... n more" notation is used on suppressed exceptions
+     * just at it is used on causes. Unlike causes, suppressed exceptions are
+     * indented beyond their "containing exceptions."
+     *
+     * <p>An exception can have both a cause and one or more suppressed
+     * exceptions:
+     * <pre>
+     * Exception in thread "main" java.lang.Exception: Main block
+     *  at Foo3.main(Foo3.java:7)
+     *  Suppressed: Resource$CloseFailException: Resource ID = 2
