Cannot open received JSON error in JMX Items

[nmz]

I have setup Zabbix server, agent and JMX in same host. Otherwise I installed tomcat in the same host. I was started tomcat with these option

-Djava.rmi.server.hostname=192.168.3.14 \
-Dcom.sun.management.jmxremote \
-Dcom.sun.management.jmxremote.port=10056 \
-Dcom.sun.management.jmxremote.authenticate=false \
-Dcom.sun.management.jmxremote.ssl=false

Plus I already setup Javagateway with above IP and port in zabbix server config file. Otherwise I also setup with same IP and port zabbix java gateway config file. But I got error as Cannot open received JSON. What am I still missing to monitor JMX items?

Please check it out log

Maybe it will be useful for someone

I had such error when I was trying to monitor application that was running on Java 1.8 by Zabbix Java gateway that was using Java 1.7. Seems like versions should match.
