JDK 27 will remove four deprecated Java launcher options: `-noclassgc`, `-verifyremote`, `-noverify`, and `-Xverify:none`. These options were deprecated in Java 13 and Java 24 respectively. After removal, using any of these options will cause the Java launcher or HotSpot VM to fail with an unrecognized option error. The `-Xverify:remote` and `-Xnoclassgc` HotSpot VM options remain unaffected and will continue to work normally.
