This is a new file and so I would just have the copyright start year.

This note was prior to module system. We could drop this comment since it's encapsulated and it's not an exported package.

nit: wrap this long line that helps future side-by-side review.

`s/newArgs/prependArgs/` to make it clearer.

Formatting consistent with jlink files:
Suggestion:
byte[] savedOptions = argfiles.stream()
.collect(Collectors.joining("\n"))
.getBytes(StandardCharsets.UTF_8);

Can this check for `java.vendor.version = XyzzyVM 3.14.15`, that will also help the reader to understand what the test tries to verify.

Same for line 94-95: check for `java.vendor.version = XyzzyVM 3.14.15` instead
