Recently, after updating to tomcat 7.0.14 (from 6.0.29), I started seeing
these pop up in catalina.out from time to time. I honestly have no idea if
it's related to the tomcat version or some legitimately wacked out
Set-Cookie header coming in. I didn't see it prior to the 7.0.14 upgrade,
but that could just be a timing coincidence. Either way I'd like to
understand the cause. Has anybody else seen this type of exception popping
up lately?

I suppose I could start logging headers, but that would get out of hand
pretty quickly...considering I only see this happen about once in 100
million requests. Anyway, figured I'd raise the flag here first...
