Yes, i have also observed this. The problem i found out is that i use
a Linked Folder in my CubicExTest project which doesn't work when you
want to use JUnit. The sollution for me was to move the commands
folder directly into the project and that solved my problem.
I am still trying to figure out if i can find a nice way of
configuring the launch configuration / classpath to see if i can keep
on using the Linked folder.
