Start with com.jagrosh.discordipc.entities.pipe.Pipe.createPipe at Pipe.java:167 and trace the UnixPipe constructor at UnixPipe.java:45, then inspect the AFUNIXSocket failure reported by NativeUnixSocket.setCreated. Reproduce or investigate the failure on macOS High Sierra with the JVM in use; done means IPC connection no longer throws the reported unsupported-JVM exception.
