Motivation: FileSourceSpec dispatcher checks can select a stale fileSource child left briefly by a previous materialization, which makes the dispatcher override assertion flaky. Modification: Capture existing fileSource children before starting each dispatcher-check stream, wait for exactly the newly materialized child, and watch it terminate after cancellation. Result: The checks assert the dispatcher of the stream started by the current test instead of a leftover child from an earlier materialization. Tests: - JDK 17 Scala 3.3.6: stream-tests / Test / testOnly org.apache.pekko.stream.io.FileSourceSpec - scalafmt --mode diff-ref=origin/main --quiet - scalafmt --list --mode diff-ref=origin/main - git diff --check References: Refs apache#2994
