Hi, I am using Drools 5.0.0.SNAPSHOT on JDK 1.6 and have noticed that there are several methods in the org.drools.repository.RulesRepository like exportRulesRepositoryToStream and importRulesRepositoryFromStream that do not throw any exceptions but does a printStackTrace instead. Could we have them throw RulesRepositoryExceptions instead J. Also, the org.drools.repository.RulesRepository.MigrateDroolsPackage does a System.out.println (could all System.out.println be logs) saying that auto-migration is complete even though no packages have been migrated on a new clean repository (seems that performed = true before any migration is performed). If I can be of any help please let me know? Thanks, Len Len Carlsen Student Systems The University of British Columbia
