sbt.TrapExitSecurityException thrown at "sbt run"

Question

I've created a simple Scala console application. I run it by sbt run and always receive the following exception on exit:

Exception: sbt.TrapExitSecurityException thrown from the UncaughtExceptionHandler in thread "run-main-0" [success] Total time: 17 s, completed 30.01.2014 22:19:37 

After that all my console output becomes invisible. I can type and run applications but I cannot see what I'm typing.

What does this exception means? What am I doing wrong?

Answer 1

// build.sbt trapExit := false 

worked for me
