Static files handler doesn't route /path/ to /path/index.html

Actual behavior (the bug) Static files config gets a 404 Not Found for the root path / and other paths ending in / (e.g. /course/), when an index.html exists in the corresponding resource folder.

Video showing behavior change when i switch to my v5 branch: https://www.loom.com/share/bb60c18b18004333a2b5c7402e960a96

Branch being used in the video: https://github.com/A1Liu/schedge/pull/141

Expected behavior I think I expected the static files config to behave the same as in v4, and respond with the resource at /next/index.html when the user goes to http://localhost:4358/

To Reproduce I made another branch with much less code that still reproduces the error, without needing to do anything too fancy: https://github.com/A1Liu/schedge/pull/149

It’s a Gradle project, so it should be build-able using Gradle, and it runs on port 4358 . After building, you can run the fat-jar directly using

java -Xmx1G -Djdk.httpclient.allowRestrictedHeaders=host,connection \
  -jar ./build/libs/schedge.jar serve

Update: Definitely a bug (at the very least an inconsistency) on our side, when setting staticFiles.precompress = false; javalin serves the index.html file, I have a fix and will PR later.
