Static files with precompress = true returns wrong data

Actual behavior (the bug) Static files serving a .js file returns wrong data when precompress = true.

Video of the behavior: https://www.loom.com/share/9066ccc851ba471b85b437ae39762fbc The video begins with the bad output, then shows good output after doing precompress = false and rebuilding/refreshing.

Screenshot:

Expected behavior the data in asdf.js is served correctly.

To Reproduce

Static files config:

config.staticFiles.add(staticFiles -> {
  staticFiles.hostedPath = "/";
  staticFiles.directory = "/next/";
  staticFiles.location = Location.CLASSPATH;
  staticFiles.precompress = true;
});

Additional context The same asdf.js file works when precompress is set to false. Other *.js files seem to work, but all the large ones seem to fail.

@vn7n24fzkq I think that is the entire file, it should be one really long line of JS, 11324 bytes long.

@tipsy This one seemed similar: https://github.com/javalin/javalin/issues/1615

Also, I can provide more information if it would be helpful, I’m just unsure what to provide.
