Failed +test on a fresh checkout of 1.5.x

Clone the repo and checkout commit 915fddbb65719ead69ebc3b110d4b15394de54f0.

Run sbt +test.

Depending on the launch script vendor and version the command above will consistently fail or will fail once before it succeeds.

For example: using vanilla sbt freshly downloaded from https://www.scala-sbt.org/ the first execution of sbt +test fails but the second execution consistently succeeds.

When you say it fails, what happens?

Apologies for the poor reporting. I was in a hurry on my way out the door. 😅 I see @mkurz explained it in detail and provided a fix.
