Since TCP/5222 is not accessible using FQDN from JVB2, JVB2 cannot connect to your JMS. Although this is a problem, it also means that your main issue is not related with the second JVB (since it is not a part of the system)
Probably JVB2 resolves the public IP of JMS and it cannot connect to it because of missing routing rule. The easiest solution is to add the local IP of JMS into the /etc/hosts file in JVB2
But this is not your main problem. Your system should work when JVB2 is closed too, IIUC it doesn’t…
