Confusion between java-rmi and rmiregistry

[Bastien Faure via dev]

Hi there,

I always wondered about how Java and RMI services worked. Since I got a
little bit more interested in them, I noticed that there might be a
confusion on nmap side about the service naming. Let's take an example:

PORT     STATE SERVICE     VERSION
9000/tcp open  rmiregistry Java RMI
9001/tcp open  java-rmi    Java RMI Registry
| rmi-dumpregistry:
|   jmxrmi
|     javax.management.remote.rmi.RMIServerImpl_Stub
|     @172.16.1.103:9000
|     extends
|       java.rmi.server.RemoteStub
|       extends
|_        java.rmi.server.RemoteObject

Port 9001 is a port that I configured as the registry, which is the
place where remote users can find stubs to retrieve. Here my registry
only contains one stub at port 9000.

So basically, may the service names be reversed ? For me the rmiregistry
should be at port 9001, not the opposite. Also, the rmi-dumpregistry
script was run on java-rmi, which comfort my position :D

Do you agree with that ?

Thanks !
