Paul Sundling commented on MPMD-67:
-----------------------------------
Forgot to mention that under further investigation, it doesn't fail, it just
prints out so many stacktraces that on a moderate size code bases it can
continuously print stack traces for a while. So you don't realize it's just
warning not failing.
