This is a malformed mapping provided. We should instead handle this and provide an appropriate message here.

gwenshap/stanleyxu2005 - I have marked this for both 1.4.6 and 1.4.7 since I think this is a simple fix and good to include into 1.4.6 also since we are respinning the RC. If you think it is too late to pull it in for 1.4.6, please remove the 1.4.6 fix version
