but thought it was an issue with jtreg. If you go to related PR,
you could see long rants about test failing with similar error.
Not sure if it would be helpful, but whoever will take on this
issue could also look into this PR for extra test case and
anything else one might find useful.</div>

<p>Could you please be more specific about the relevant parts in the
PR? I went through it twice, but sadly don't see much that would
be relevant. (I believe this report is specifically about
sub-optimal error recovery and reporting for implicitly declared

<p>It appears that you are missing a "void" return
type before the main() method name. As noted in
the JEP-477, it should be:</p>
<p>import module java.base;<br>
void main() {<br>
println("Moose");<br>
}</p>

</div>
<div>that said, if we want beginners to be able to
use that syntax, the error message should be
changed because the current message is misleading
and not very helpfull (javac should recognize
"main" and have a tailored error message).<br>
</div>
<div><br>
</div>
<div>@Ken, you do not need to import module
java.base, it's done by default and --source 23 is
not needed anymore since 23.<br>
