Question

[#|2015-08-04T05:10:40.077+0000|SEVERE|glassfish3.1.2|javax.enterprise.system.std.com.sun.enterprise.server.logging|_ThreadID=83;_ThreadName=Thread-2;|java.lang.RuntimeException: Port 8686 is not available for the internal rmi registry. This means that a call was made with the same port, without closing earlier registry instance. This has to do with the system jmx connector configuration in admin-service element of the configuration associated with this instance

I made sure that none of the process is using port 8686 using netstat command still i am getting the same issue.

Answer 1

try this

1) netstat -a -o -n and it will bring up a network list,search for the local address like 127.0.0.1:8686 and note the PID (eq 3624).

2) taskkill /F /PID 3624 . Run this command to kill that process.

Answer 2

This appears to be a known bug in Glassfish, qv here . Could you try upgrading to Glassfish 4.x ? The bug is reported as being fixed, but I'm not sure which version 3.x has the fix in it. You should be fine with Glassfish 4.x so long as you have JDK 7 and above.

With regards to the cause of this bug, here is an excerpt from the link I cited above:

I did some investigation and found that our startup code calls LocateRegistry.createRegistry(), but shutdown code never unexports the registry, so subsequent createRegistry fails. Look at the discussion 1 to understand what needs to be done.
