Darius, CHICA encountered a major issue with Logic yesterday. We had information get crossed between multiple patients, and we tracked it down to a thread safety issue in Logic. Currently the Token Service's "getRule(String)" method (in OpenMRS 1.7) retrieves a rule from a rule provider and then caches it. The next time the rule is asked for, it gets pulled directly from the cache. Our Java rules translated by the Arden translator had class level variables that were getting changed by concurrent threads, and we were seeing incorrect data for patients.
In OpenMRS 1.5 the logic service would cache the rule, but it would return a new instantiation of the rule class so it was thread safe. Now in 1.7 + the thread safety no longer exists because the same instance of the rule is directly returned from the cache. This is a very high priority issue that needs to be resolved immediately.
