[2/4] brooklyn-server git commit: Adds tests which trigger the root cause leading to failures in testChildFailuresOnStartButWithQuorumCausesAppToSucceed

Posted by dr...@apache.org.
Adds tests which trigger the root cause leading to failures in testChildFailuresOnStartButWithQuorumCausesAppToSucceed

The tests are indeterministic - fail a couple of times per 100 invocations when executing with "mvn test" in the brooklyn-itest docker container.

[3/4] brooklyn-server git commit: Fixes the deduplication logic in AbstractEnricher

Posted by dr...@apache.org.
Fixes the deduplication logic in AbstractEnricher

Could incorrectly deduplicate (for example result in setting the same value twice) when the value is set from parallel threads.
