Tomcat 7 JMX not showing any threads in jconsole

I've enabled JMX in Tomcat 7 and I can see most of the data in JConsole and VisualVM, except for the threads. It not reporting any JVM thread data (but does report heap and CPU data).

What am I doing wrong?

enter image description here

Tomcat 7.0.59 running on FreeBSD 10.1 (amd64). OpenJDK 64-Bit Server VM version 24.80-b11. JMX enabled with startup parameters: "-Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=xx.xx.xx.xx -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"

Edit (or create) $CATALINA_HOME/bin/setenv.sh

export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote"
export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.port=11999"
export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.ssl=false"
export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.authenticate=true"
export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.password.file=$CATALINA_HOME/conf/jmxremote.password"
export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote.access.file=$CATALINA_HOME/conf/jmxremote.access"

$CATALINA_HOME/conf/jmxremote.access:

****grant readwrite access for your account then you can see threads****
yourAccount readwrite

$CATALINA_HOME/conf/jmxremote.password:

yourAccount yourPassword

And then change mode for these files:

$chmod 600 $CATALINA_HOME/conf/jmxremote.access

$chmod 600 $CATALINA_HOME/conf/jmxremote.password

Then start your Tomcat and login with right ip, port, account and password.
