sbt-scalafix (sometimes) crashes on Linux

[ahoy-jon]

We have this issue on Linux, but not in IntelliJ-sbt-shell on the same machine.

Does that speak to anyone?

Cheers, Jonathan

[bjaglin]

That does not ring a bell. I understand the failure happens only when you run scalafixAll explicitly from the (non-IntelliJ) shell, right?

To help investigation,

1. Is it always the same file in the stack trace?
2. What other sbt plugins do you have in the project?

[ahoy-jon]

It was always the same type of trace on the same machine. We suspect it was some competition between compilers (intellIj + console) using .bloop. The bug is not reappearing for now.
