Subject [jira] [Commented] (KARAF-3114) Call to ManagementFactory.getPlatformMBeanServer() fail due to RBAC
Date Tue, 15 Jul 2014 12:53:05 GMT

    [ https://issues.apache.org/jira/browse/KARAF-3114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14062015#comment-14062015

Guillaume Nodet commented on KARAF-3114:
----------------------------------------

When run from the command or JMX, the user needs to have the required role to perform the
heap dump, but that should not otherwise be an issue I think.

> With the introduction of the RBAC support to secure the JMX layer, a simple ManagementFactory.getPlatformMBeanServer()
fails with something like:
> {code}
> java.lang.NullPointerException

> A workaround is to use a JMXServiceURL and JMXConnector instead, but it could be disturbing
for the users.
