+ * @summary This test verifies that the HttpClient works correctly when the server
+ * sends a large certificate. This test will not pass without
+ * the fix for JDK-8231449. To regenerate the certificate, modify the
+ * COMMAND constant as you need, possibly changing the start date
+ * and validity of the certificate in the command, then run the test.
+ * The test will run with the old certificate, but will print the new command.
+ * Copy paste the new command printed by this test into a terminal.
+ * Then modify the at run line to pass the file generated by that command
+ * as first argument, and copy paste the new values of the COMMAND and
+ * BASE64_CERT constant printed by the test into the test.
+ * Then restore the original at run line and test again.
