This is not a problem of the runner (even if it looks as such) but of the data. 
Unfortunatelly $() method doesn't work nicely with nulls. As a workaround use 
normal new Object[] {null} when passing nulls and it works just fine.

I was hit by it again. I don't like to remember about workarounds. I had a look 
at the code.

You're correct. That's not a problem of the junitparams runner. Rather, a 
limitation of Java var-args. But it's reported by junitparams in a misleading 
way.

Nevertheless, the workaround could be moved from users code to the project 
itself. I've pushed it together with tests to a clone 
(http://code.google.com/r/rafalwicha-solving-issue-23/source/browse). I'm also 
attaching a throw-away project with null cases.

Could you please have a look at it and merge to the next release? I assure at 
least 10 users will be glad for it.
