Java seems to have issues creating a UnixDomainServerSocket when using the persistent storage feature. This has been observed on the hosted instance che.openshift.io.
Is that something to be expected?

I'm not sure that it is indeed the case, more detailed investigation would be needed to have 100% proof.

But it would explain, why there are issues when importing a Scala project on Che (with persistent storage). sbt (the Scala build tool), during the import of the project, tries to create a Unix socket on the filesystem but doesn't seem to be able to do so. That causes it to get into a weird state, which blocks the import.

It is reproducible by creating a new Scala project from the available template.

Issue on Metals (the Scala language server) scalameta/metals#2235
Issue on sbt sbt/sbt#6101
