Thanks for the thorough investigation, we’ll make sure to get this bug addressed in the next release.

This could lead to surprises and explain some undefined behaviors for some people so it's good to point it out, and maybe you should fill some bug report on spring website in order to inform them asap about this problem. I think lazy-init is not really needed though for singletons. Loading the beans at startup time is not a big cost and let's you avoid a lot of problems.
