javapc's HoverTermSuite fails on JDK 21

[SethTisue]

this came up in the Scala 2 community build:

-public interface java.util.List<E> extends java.util.SequencedCollection<E>
+public interface java.util.List<E> extends java.util.Collection<E>

Thanks for the report @SethTisue, it looks like we don't account for differences in the JDK versions in the suite. It should be a fairly quick fix.

EDIT: Just adding a note in here to say that I haven't forgotten about this, just cs doesn't have any 21 versions yet, and that's what I use to get my Java. So as soon as that appears I'll look further at this.

Looks like @tgodzik started the work on #5758
