Hi @fniephaus
did a small change in a markdown file and afterwards the test https://github.com/actions/setup-java/actions/runs/13272353142/job/37054560743?pr=750 runs in an error because downloading https://download.oracle.com/graalvm/18/latest/graalvm-jdk-18_macos-x64_bin.tar.gz runs in a 404

We're sorry, the page you requested was not found.
We have recorded this error (404) to help us fix the problem.
You may wish to try again using one of the tools below.

Can you please check?

Hi @skateball,

I'm not sure why this is failing but this seems to be a transient issue. GraalVM for JDK 18 indeed does not exist and the test is supposed to check for exactly that. Instead of an exception being thrown, however, I see this in the log:

Received promise resolved instead of rejected

I'd assume this is unrelated to your markdown changes.
