Cannot run coreference resolution

[Marco Cornolti]

Hello,

I am trying to launch the Factorie NLP server with pre-built models. Everything works fine until I try to run coreference resolution with --parse-lexical-coref or --parse-forward-coref. In both cases, when I issue a call through the socket, I get the following exception thrown (and the server returns nothing):

Exception in thread "main" java.lang.Error: No file named Nothing$.factorie found in classpath for class scala.runtim
e.Nothing$, and no value found in system property scala.runtime.Nothing$. To fix this either add a file with the righ
t name to the classpath or set the system property to point to a directory containing the file.

Do you have any insight on why this happens, or how to solve the issue?

Thanks,
