Monitors schedule tasks that are executed periodically
and which go fetching the monitored attribute's value
from the MBean.

When security is active, the security checks carried out
to see if the caller has access to the attribute or to any
security protected operation the attribute implementation
might perform are based on the access control context of
the monitor.start() caller and not on the access control
context of the monitor creator.
