Zabbix jmx "java.lang.RuntimeException: Operation failed with status WAITING"

[Mick]

Hello, I have zabbix ver. 2.2.1 and in my zabbix proxy I have some problem with java_gateway. In Frontend I see this error below interface:

"java.rmi.UnmarshalException: error unmarshalling return; nested exception is: java.io.EOFException"

I attach log file from zabbix_java_gaeteway

Please give me some advice

Regards
Mick
