Per [this CSR comment](https://bugs.openjdk.org/browse/JDK-8301905?focusedCommentId=14559000&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14559000) it was requested to make this an error for source versions >= 21 and a warning for source versions prior to 21.

In order to satisfy `diags/CheckExamples.java` I needed an example that would generate the warning.

But I guess you're right... so the alternative would be to add `compiler.warn.extraneous.semicolon` to `diags/examples.not-yet.txt`?
