You use Double-Checked Locking in
org/openemcee/microflow/frontend/MicroflowFactory.java,
but that's not guaranteed to work.

Hi,

Thank you very much for the feedback. This should be ok due
to the fact that the double-checked locking is used as a
performance tweak. If 2 threads get in the intializer
block, we'll simply process the configs twice, and last in
to the cache wins.

Regards,

Scott
