> The exception is thrown in org.drools.rule.JavaRuntimeDialectData, when the CompositeClassLoader tries to define the class implementing a rule consequence. The method fastFindClass, which does the lazy initialization, is not thread-safe. It is possible for two threads to call findLoadedClass(..), get null and thus start the definition process which eventually results in the exception.
> The situation is indeed very rare
