Hey Jeff, On phone so apologies for brevity. This is the same root cause as MINIFI-405. Not expected and biproduct of the classpath issues from before and associates transitive dependencies getting lost in the process. If you would like to add on to 405 with your config as an additional verification case can certainly also evaluate in fixing
