> ---------------------------------------------------------
>

> URL: https://issues.apache.org/jira/browse/KARAF-4351
> Project: Karaf
> Issue Type: Improvement
> Components: karaf-security
> Affects Versions: 2.4.4, 3.0.6, 4.0.4
> Reporter: Grzegorz Grzybek
>
> We've scenario where there are 2000 ActiveMQ queues running in Karaf with
> hawtio that leverages RBAC.
> hawtio, through Jolokia library calls
> {{org.apache.karaf.management.JMXSecurityMBean#canInvoke(java.util.Map<java.lang.String,java.util.List<java.lang.String>>)}}
> method passing map of >2000 MBeanNames to lists of average size = 20.
> Thus we have >40000 calls to one of
> {{org.apache.karaf.management.internal.JMXSecurityMBeanImpl#canInvoke()}}
> methods for pairs of MBean+signature and we have equal number of calls to
> {{org.osgi.service.cm.ConfigurationAdmin#listConfigurations("(service.pid=jmx.acl*)"}}.
