Are the following still required in 5.5+

conf/jmx.access:

# The "monitorRole" role has readonly access.
# The "controlRole" role has readwrite access.
monitorRole readonly
controlRole readwrite

conf/jmx.password:

# The "monitorRole" role has password "abc123".
# The "controlRole" role has password "abcd1234".
monitorRole abc123
controlRole abcd1234


 I don't have the following set in /etc/default/activemq.

  SUNJMX="-Dcom.sun.management.jmxremote.port=1616
-Dcom.sun.management.jmxremote.ssl=false \
    
-Dcom.sun.management.jmxremote.password.file=${ACTIVEMQ_BASE}/conf/jmx.password
\
    -Dcom.sun.management.jmxremote.access.file=${ACTIVEMQ_BASE}/conf/jmx.access"


Is this still required in 5.5+ ?

My activemq.xml reads:
