last green build Mar 21: https://scala-ci.typesafe.com/view/scala-2.12.x/job/scala-2.12.x-integrate-windows/925/ first red build Mar 22: https://scala-ci.typesafe.com/view/scala-2.12.x/job/scala-2.12.x-integrate-windows/926/ the failures are: * `!! 1106 - run/t4841-isolate-plugins` * `!! 1562 - run/t7634.scala` * and `test/scalacheck/sanitycheck.scala` @retronym all three look to me like minor fallout from your partest changes. 2.13.x is red as well (at e.g. https://scala-ci.typesafe.com/job/scala-2.13.x-integrate-windows/539/consoleFull), the failures are the same
