+ [#usingjmxclients|Using JMX clients]
+ When running a JMX client (JConsole, VisualVM) on the same machine as the target JVM process
it is possible to connect without pre-configuring a JMX port, using the local connector stub.
 This method relies on being able to create a protected temporary file, accessible only to
a user with administrator privileges.  Java processes which are accessible via the local connector
will automatically appear in the client.
+ NB On Windows, this means that the temporary directory must be located on an NTFS formatted
disk.  See the following link for more details.
+ [[| JConsole and Remote
Management FAQ]]
+ From Java 6 a process needn't have the management agent enabled when it starts, as the Attach
API permits the management agent to be activated on demand.
