Created attachment 193731 [details]
draft patch, in case could not reproduce

I had try to reproduce the defect without luck, meanwhile I have prepare just a validation to avoid the NPE.

> Israel, what version of WTP do you intend for this patch to go in?

since I were not able to reproduce it, 3.2.4 should be good, but maybe optional if pmc approval is really necessary, 3.3 is good unless someone else has got this same issue.

Comment 4 Carl Anderson

Committed to HEAD for WTP 3.4.0.
