Effectively, it searches for `18`. But a second `18` could get to version string from anywhere: the Git hash, the user name, etc. It is failing in current GHA due to Git hash containing `18`.

Checking that lines start with "javac" handles the case of accidental version strings that includes that string (think username that includes "javac" for some reason, who are we to judge...).

It would seem better to me if the test didn't depend on hardcoded localized strings (e.g. by printing the content of e.g. `javac --help` and checking the result is the same for `javac --help --help`; or by reading the bundle and using it as a template; or by checking if there are any duplicate line if the output), but since the test didn't do it originally, I don't think it is a stopper.
