According to the servlet specification (SRV.6.2.1) for each <filter> definition
only one instance is instantiated per JVM.
The current implementation of JMXOpsAccessControlFilter stores the roles of the current
user in a member variable, if there are mutliple calls simultaneously there will be a race
condition one call can receive the permissions of the other user.
