Description

OAK-3477 changed the naming convention of JMX Mbeans created by oak. Originally the DocumentNodeStore was created as follows:

domain/type/name/properties
org.apache.jackrabbit.oak	"DocumentNodeStore"	"Document node store management"	{id=6}

while OAK-3477 changed that to:

domain/type/name/properties
org.apache.jackrabbit.oak	DocumentNodeStore	Document node store management

(meaning, the type is not quoted anymore, plus the id is gone)

This breaks the query used in SynchronizedClocksHealthCheck to get the DocumentNodeStoreMBean (fyi Chetan Mehrotra). Currently this results in the health check to report that: "Intra-cluster test n/a (No DocumentNodeStore MBean found) " - ie it goes rather unnoticed and effectively the health-check is disabled. So we need to adjust the query in SynchronizedClocksHealthCheck.
