    Description

      If you use a fact class named "D", you will hit errors during executable-model code generation.

          @Test
    public void testClassNameConflict() {
        String str =
                "import " + D.class.getCanonicalName() + ";" +
                "rule R when\n" +
                "  D(name == \"John\")\n" +
                "then\n" +
                "end";

        KieSession ksession = getKieSession( str );

        D fact = new D("John");
        ksession.insert( fact );
        assertEquals(1, ksession.fireAllRules());
    }

    public static class D {

        private String name;

        public D(String name) {
            this.name = name;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

    }
