Due to an issue with reloading persisted sessions that contained a cron timer rule, I upgraded to 6.1.0.Beta3. Now I'm encountering a problem with a threaded fireUntilHalt command (cannot be issued on a persisted session). Exception in thread "SimpleAsyncTaskExecutor-1" java.lang.UnsupportedOperationException: Command session.fireUntilHalt(); cannot be issued on a persisted session at org.drools.persistence.SingleSessionCommandService$TransactionInterceptor.execute(SingleSessionCommandService.java:474) at org.drools.persistence.SingleSessionCommandService.execute(SingleSessionCommandService.java:353) at org.drools.core.command.impl.CommandBasedStatefulKnowledgeSession.fireUntilHalt(CommandBasedStatefulKnowledgeSession.java:272)... It worked without issue in 6.0.1.Final. Though I suspect not, is this expected behaviour? Alternately, are there configuration/other changes that must be implemented.
