Is there any reason we don't use the `java`, something else in the image, or even something built as part of the test-image.

To be fair, this looks similar to what `isMusl()` does: searching for strings in outputs. But I do wonder if `--help` would include "sleep" for some innocuous description somewhere, and this code would accidentally match. @lutkerd, what's the output for `coreutils --help` for a single executable binary?
