[CodeReviewer] Works with Mavericks?

I upgraded my computer to OSX 10.9 yesterday evening, and today am getting some weird errors from code collab.  Mostly, the gui seems unable to get status on collabs, and the command line client spits out error messages like:

ERROR: Executing command `ccollab addchangelist`:

Unexpected exception, possibly internal error.

Please report to support@smartbear.com.

 

java.lang.NullPointerException
