can you see why i get a warning from org.jetbrains.idea.maven.server.RemoteMavenServer.main(RemoteMavenServer???

What happens is IDEA starts a process with Maven server and then tries to connect to this process for control using RMI.

The server binds: https://github.com/JetBrains/intellij-community/blob/6d7d268c32e469f0bfb77e9f0021c8f74b493bc3/platform/util-rt/src/com/intellij/execution/rmi/RemoteServer.java#L75-L75

Then it checks if binding has worked: https://github.com/JetBrains/intellij-community/blob/6d7d268c32e469f0bfb77e9f0021c8f74b493bc3/platform/util-rt/src/com/intellij/execution/rmi/RemoteServer.java#L88-L88

And here is where it fails with java.rmi.NotBoundException: _DEAD_HAND_ you see in the log.

You can try running server/client RMI samples to see if they produce the same error:

Hi,

i tried your advise. the rmi test has worked without any problems

http://www.ejbtutorial.com/java-rmi/group-chat-example-using-java-rmi-with-a-graphical-user-interface

What can i do to fix my maven problem?

Did you run RMI tests on the same Java version as IDEA uses (https://intellij-support.jetbrains.com/hc/articles/206544879) and with

-Djava.net.preferIPv4Stack=true

JVM option that is used in IDEA by default? IDEA and Maven run on Java from

/Applications/IntelliJ IDEA.app/Contents/jdk/Contents/Home/jre/bin/java

on your system.

Could be related to how your networking/protocols are configured on Mac.

I tried your advise

without  -Djava.net.preferIPv4Stack=true it works fine

with the JVM Options it get  this message:

on Server:

Chat Server failed: java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: 

java.net.ConnectException: Operation timed out

on Client:

java.rmi.NotBoundException: myabc

So it seems the JVM Option is, in this case, not set correctly. 

How can i change this options? Please send me the right directory an file.

Thanks

Remove this option from the .vmoptions file, see https://intellij-support.jetbrains.com/hc/articles/206544869.

Dear Serge

it works now, thanks
