steps

Start sbt in an "unusual" filesystem, fox example, in Eclipse Che, which is a containerized, cloud IDE, where the filesystem sbt works with is mounted over network.

problem

The whole message is this:

sbt server is already booting. Create a new server? y/n (default y)

sbt prints it even at wrong times.

expectation

It seems enough to just press Enter or y and Enter, and sbt then continues, but it shouldn't be displayed in the first place, because no sbt server has started yet.

notes

Other instance is this StackOverflow question, where there were issues with Windows' wsl2:

It may be causing issues for other tools depending on sbt: scalameta/metals#2235
