ruleBase.addPackage(packageBuilder.getPackage()); should fail-fast with a clear error message if the packageBuilder has any errors ---------------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-2079 URL: https://issues.jboss.org/browse/JBRULES-2079 Project: Drools Issue Type: Feature Request Security Level: Public(Everyone can see) Components: drools-core Affects Versions: 5.0.0.CR1 Reporter: Geoffrey De Smet Assignee: Mark Proctor Priority: Minor Fix For: 5.2.0.CR2 After you 've build your package with packageBuilder, you've either called the hasErrors() method and done something about it or you didn't check the hasErrors() method because you didn't know (or want to know) it existed and you expect it to throw an exception because hasErrors() returns true. The principle of least surpise. You don't expect that it continues like everything is cool (while it's not) and crashes the moment you fire your first rules. The exception should be a runtime exception and the message should at least mention the first of the errors. The exception should probably contain a list of all errors of course too as a property. See InvalidStateException in hibernate-validator.
