Hazelcast JMX & multiple apps on the same server

[Jean Luc]

We have several apps using Hazelcast 3.4.2. When more than one of them is deployed on the same server (in this case JBoss EAP 6.3 or 6.4), a typical scenario for developers, adding -Dhazelcast.jmx=true leads to the error below (perhaps of relevance is that we also set hazelcast.group.name explicitly). I think including the app name or the the TCP port (so that we get a unique name) would help. Or is there any existing workaround?

Thanks a lot,

JL
