Minor thing, but confusing for newbies and it might break the tutor build when we want to release, because starting up a REPL does not expect any output.

I think I fixed this some time ago by removing all explicit log4j calls in Rascal proper. I'll have another look

[jurgenvinju]

@rodinaarssen is this fixed?

[rodinaarssen]

@jurgenvinju no, this is still there

[rodinaarssen]

This log message now also appears in REPLs for Rascal projects that do have a dependency on rascal-lsp. As rascal-lsp is no longer automatically added to the class path/path config, for such projects, there is no logging provider
