Cannot reproduce. Using your code on OS X with two minor modifications:

1. Connect to my own user on localhost port 22.
2. Use public-key authentication instead of password authentication.

Both running main or running the unit test work, ls or ls -l do show the expected output.

Thank, I think I need to check my ide.

Idea needs to add -Deditable.java.test.console=true options
