Ok, I am too late, but just for the record: I let your old patch (including timeout adjustments) run in our test infrastructure and it fixed the timeout issue from [JDK-8271613](https://bugs.openjdk.java.net/browse/JDK-8271613).

Probably it could be a better solution to add the stress keyword for slow running or high load tests - like it is done in the hotspot part of the tests. Then automated test run can exclude or select these test by keyword.
