The test failed because the shared HttpClients were not garbage collected in the imparted time. The timeout of 500ms to wait for the clients to clean up is sufficient most of the time but rather small, I suspect a bit more time was needed in that instance.
The fix raises the timeout to 1500ms. ------------- Commit messages: - 8333804 Changes: https://git.openjdk.org/jdk/pull/19600/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=19600&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8333804 Stats: 1 line in 1 file changed: 0 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/19600.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/19600/head:pull/19600 PR: https://git.openjdk.org/jdk/pull/19600
