Java 9 Not Supported

[raarts]

Hi. I'm a new user. I am unable to connect to my iex instance. Started with:

iex --name wobble@localhost --cookie mycookie -S mix phx.server

The connection window does show the instance:

using wobble@localhost does not make a difference. Node.self() prints :wobble@localhost

java --version
java 9.0.1

Hi Ron
Can you call node() (or the elixir equivalent) to double check that wobble is the full name of the node you're trying to connect to? It may be wobble@localhost.

Not sure what the NoClassDefFoundError is about. If you're running from a jar with all the deps, you could check that the class com.moandjiezana.toml.ValueWriters exists in the jar.

Yes, Node.self() returns :wobble@localhost.
Not being a java person. I used the standard quick-start one-liner to install, and use java -jar target/*runnable.jar to start it.

unzipping the jar file I found this: ./com/moandjiezana/toml/ValueWriters.class , but otherwise I could not find . -name \*ValueWriters\* anywhere in the repo, so I guess it's a dependency.

I'm able to reproduce this error when I run on java 9, only 8u20 or higher is supported.

This is because of the module changes which appears to break all calls to dependencies.
