Description

With OAK-3477 the JMX MBean registration logic would log a warning (earlier it was getting eaten up) if there is some issue in registering the MBean. With that change now running any benchmark in oak-run logs following warning

14:20:13.674 [main] WARN  org.apache.jackrabbit.oak.Oak - Unexpected exception while registering MBean of type [interface org.apache.jackrabbit.oak.api.jmx.QueryEngineSettingsMBean] against name [org.apache.jackrabbit.oak:name=settings,type=QueryEngineSettings]
