Problem with Scala 2.12.1 on Mac OS X

[Łukasz Biały]

Hey guys, I was trying to use drip with Scala and fish shell on Mac OS X and it caused me some pain today. It seems it keeps creating new processes and never kills those it used before. If I ps aux | grep -c drip now it counts 1080 hits (590 for drip_daemon so this is probably the true process count). I am using Scala both as REPL and in Intellij Idea (latest). I've added those lines to my fish.init files as docs suggested:

set -gx JAVA_HOME (/usr/libexec/java_home)
set -gx PATH $JAVA_HOME/bin $PATH
set -gx JAVACMD drip

and everything was nice and speedy, but I started to run out of processes. I upped my ulimit and launchctl's maxproc's limits, but I kept getting fork errors and started looking at my ps aux output. Here's the command that keeps repeating 590 times now:

Any ideas, am I doing something ridiculously wrong?

Apparently I was wrong, there really were 1080 processes of drip - second one was:
