In the following test case:

{code}
        @Test
        public void testAlphaIndexing() throws Exception {
            String drl =
                    "    package org.drools.test; " +
     
                    "    declare ObjectB " +
                    "       name : String " +
                    "       intValue : Integer " +
                    "    end " +
     
                    "    rule 'insert object' " +
                    "       when " +
                    "       then " +
                    "           insert( new ObjectB( null, 0 ) ); " +
                    "    end " +
     
                    "    rule 'rule 1' " +
                    "       when " +
                    "           ObjectB( intValue == 1 ) " +
                    "       then " +
                    "    end " +
     
                    "    rule 'rule 2' " +
                    "       when " +
                    "           ObjectB( intValue == 2 ) " +
                    "       then " +
                    "    end " +
     
                    "    rule 'rule 3' " +
                    "       when " +
                    "           $b : ObjectB( intValue == null ) " +
                    "       then\n" +
                    "           System.out.println( $b ); " +
                    "    end" +
                    "\n" ;
     
            KieHelper helper = new KieHelper();
            helper.addContent( drl, ResourceType.DRL );
            assertTrue( helper.verify().getMessages( org.kie.api.builder.Message.Level.ERROR ).isEmpty() );
            helper.build(  ).newKieSession().fireAllRules();
        }
{code}

rule 3 fires even if it shouldn't
