+ * @bug 8217375
+ * @summary This test runs those test cases of {@link Compatibility} test nearby
+ * which can be executed within the currently built and tested JDK and without
+ * TSA, with only one digest algorithm and with only one key (algorithm and
+ * size) and without delayed verification.
+ * Other test cases are to be executed manually invoking {@link Compatibility}
+ * involving more than the currently built and tested JDK verifying the
+ * compatibility of jarsigner across different JDK releases.
+ * For more details about the test and its usages, please look at the README.
