------------------------------------------

             Summary: InstanceNotFoundException appears in the log when a cache is closed and MBeans are disabled
                 Key: IGNITE-7398
                 URL: https://issues.apache.org/jira/browse/IGNITE-7398
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.4
            Reporter: Stanislav Lukyanov
            Priority: Minor


If IGNITE_MBEANS_DISABLED is set to true, whenever a cache is started the following error is logged:
javax.management.InstanceNotFoundException: org.apache:clsLdr=18b4aac2,igniteInstanceName=mbeans.GridMBeanDisableSelfTest0,group=Cache groups,name=MyCache

That's because GridCacheProcessor::cleanup unconditionally attempts to unregister cache's MBean, not checking whether or not the cache actually has an MBean registered for it.
