FYI, this is possible now in JDK 26+ using the `-Werror` flag.
```
$ javac --help
...
-Werror Terminate compilation if any warnings occur
-Werror:<key>(,<key>)*
Specify lint categories for which warnings should terminate
compilation,
separated by comma.
Precede a key by '-' to exclude the specified category.
Use --help-lint to see the supported keys.
```
Caveat: [there is a bug](https://bugs.openjdk.org/browse/JDK-8349847) in the
implementation that will be fixed in 27.
