+ * huge number of lines which can be specified via <code>LINE_NUMBER</code>
+ * <code>NUMBER_OF_ITERATIONS</code>
+ * times (by default 1000 times) and fails
+ * <ul>
+ *     <li>by <code>java.lang.RuntimeException: Waiting for the invocation event timed out</code> if it hangs because of
+ *     the deadlock <code>at sun.lwawt.macosx.CPlatformComponent.$$YJP$$nativeCreateComponent(Native Method)</code> as
+ *     it was described in JRE-401</li>
+ *
+ *     <li>or by <code>java.lang.RuntimeException: The test is near to be hang</code> if the method
+ *     <code>Popup.show()</code> was executed <code>HANG_TIME_FACTOR</code> times longer than it was executed on the
+ *     first iteration.
