It is more than just the initialisation path you need to be worried
about. I'm not sure what the exact rule is, but it wouldn't surprise me
if it is "never block on a management op from any code the container has
called".
For example using a management op from a servlet service method (e.g.
doPost) is dangerous because there may be an op in progress that is
waiting for all servlet processing to finish before it does it's work.
