A likely fix is to just not store a ref to coordinatorEnvironmentBean in TransactionSubsystemRootResour<wbr>ceDefinition$<wbr>StatisticsEnabledHandler. Just find it and use it in applyUpdateToRuntime/<wbr>revertUpdateToRuntime neither of which will get called before system properties are set. They don’t get called at all if the user doesn’t do a write-attribute op to change that attribute.<br>
