    Description

      If enabled RBAC, InstanceNotFoundException is thrown when getting jboss.as and jboss.as.expr MBeans from application on EAP.

      ERROR [stderr] (default task-1) javax.management.InstanceNotFoundException: WFLYJMX0017: No MBean found with name jboss.as:subsystem=datasources,data-source=ExampleDS,statistics=pool
ERROR [stderr] (default task-1) 	at org.jboss.as.jmx.model.ResourceAccessControlUtil.getResourceAccessWithInstanceNotFoundExceptionIfNotAccessible(ResourceAccessControlUtil.java:72)

...

      The exeption can be occurred by getting mbeans via MBeanServer as in-vm access as follows,

      import java.lang.management.ManagementFactory;
import javax.management.MBeanServer;
...
String objectname = "jboss.as:subsystem=datasources,data-source=ExampleDS,statistics=pool";
MBeanServer server = ManagementFactory.getPlatformMBeanServer();
Object r = server.getAttribute(new ObjectName(objectname), "ActiveCount");

      If connect via JMXConnectorFactory as followis, the mbeans can be gotten.

      import javax.management.remote.JMXConnectorFactory;
import javax.management.remote.JMXConnector;
import javax.management.remote.JMXServiceURL;
import javax.management.MBeanServerConnection;
...
String objectname = "jboss.as:subsystem=datasources,data-source=ExampleDS,statistics=pool";
JMXServiceURL jmx_service_url = new JMXServiceURL("service:jmx:remote+http://" + host_name + ":" + port);
JMXConnector jmx_connector = JMXConnectorFactory.connect(jmx_service_url, null);
MBeanServerConnection conn = jmx_connector.getMBeanServerConnection();
conn.getAttribute(new ObjectName(objectname), "ActiveCount");
