Description

Continuum seems to be unable to checkout from the SCM (subversion). As a result, the working copy directory is apparently empty.

Clicking on the "/continuum/servlet/continuum/target/WorkingCopy.vm/view/WorkingCopy/id/1" link results in a blank page being displayed, and the following stack trace being loggedin logs\wrapper.log :
