      This keeps up reported as Flaked tests as it seems to clash with some other test (related activity) and gets retried correctly. (Using synchronized mocks makes no difference).

      Reproducible by https://github.com/jenkinsci/resource-disposer-plugin/commit/bc5f00008cc31a680e103dd7bd804bd64b0a4668 and mvn clean package. Not by mvn clean package -Dtest=AsyncResourceDisposerTest#combined of course.
