Zabbix JavaGateway in docker malfunction

[geostant]

I'm running zabbix in docker,
I'm running 4 containers:

1. mysql:5.6
2. zabbix-server-mysql:3.4.1
3. zabbix-web-nginx-mysql:3.4.1
4. zabbix-java-gateway:3.0.12

I've enabled zabbix java gateway in my zabbix server
and setup my application to except remote jmx connection - with jconsole I can connect without any issues.

I've set my host inside zabbix for jmx monitoring and used the premade template for jmx (generic).

Inside the zabbix java gateway logs I can see the following error:

DEBUG c.z.gateway.BinaryProtocolSpeaker - received the following data in request: {"request":"java gateway jmx","jmx_endpoint":"service:jmx:rmi:///jndi/rmi://192.168.1.10:12345/jmxrmi","keys":["jmx[\"java.lang:type=Threading\",ThreadCount]"]}
WARN com.zabbix.gateway.SocketProcessor - error processing request com.zabbix.gateway.ZabbixException: org.json.JSONException: No value for conn

I've no clue what to do and any help will be highly appreciated.


Thanks !

I've upgrade my java gateway docker instance to 3.4.3 and that solved my issue.
