[jira] [Created] (OAK-9417) ClassCastException in ConsolidatedListenerMBeanImpl

Carsten Ziegeler created OAK-9417:
-------------------------------------

             Summary: ClassCastException in ConsolidatedListenerMBeanImpl
                 Key: OAK-9417
                 URL: https://issues.apache.org/jira/browse/OAK-9417
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: core
    Affects Versions: 1.38.0
            Reporter: Carsten Ziegeler


The ConsolidatedListenerMBeanImpl makes a wrong assumption that the value of the jmx.objectname service registration property always is an ObjectName - String is also a valid and allowed type. If a String is used a ClassCastException is thrown:
{noformat}
[org.apache.jackrabbit.oak.jcr.observation.ConsolidatedListenerMBeanImpl(268)] : The bindBackgroundObserverMBean method has thrown an exception (java.lang.ClassCastException: class java.lang.String cannot be cast to class javax.management.ObjectName (java.lang.String is in module java.base of loader 'bootstrap'; javax.management.ObjectName is in module java.management of loader 'bootstrap'))
{noformat}
