We have a good understanding as to why the test case RemovalTimeStrategyEndTest#shouldResolveHistoricActivityInstanceInConcurrentEnvironment is failing randomly only on MariaDB, MySQL and CockroachDB.
Hints (Optional):
The test case has been introduced with CAM-13094 to ensure we prevent deadlocks on MSSQL on concurrent removal time updates
Those deadlocks are randomly occurring on MariaDB, MySQL and CockroachDB for that test case
The test case has been disabled on MariaDB, MySQL and CockroachDB for now
The test case has been added to 7.14 and 7.15 with CAM-13094 but might be present on other versions as well in the meantime if there was a need to patch this further down
