Avoid unnecessary IllegalStateException
Avoid empty error message

Issue:

https://github.com/apache/incubator-kie-drools/issues/5915

This PR actually just removes the IllegalStateException and fixes only org.drools.compiler.integrationtests.drl.DRLTest#testWithInvalidRule2 in the failing tests in the GH issue . Other tests are explained in the comments of the GH issue and will be dealt by other PRs.
