             Summary: ClassObjectTypes are not all correctly rewired during a packages merge
                 Key: DROOLS-1219
                 URL: https://issues.jboss.org/browse/DROOLS-1219
             Project: Drools
          Issue Type: Bug
          Components: core engine
            Reporter: Mario Fusco
            Assignee: Mario Fusco


As demonstrated by the following not all ClassObjectTypes are correctly rewired during a package merge. In that case R2 doesn't fire because the ClassObjectType used by the from pattern is not rewired to the new Class instance created by the second ProjectClassLoader.

    @Test
    public void testWiringClassOnPackageMerge() throws Exception {
        String drl_init =
                "package init;\n" +

                "rule RInit when\n" +
                "then\n" +
                "    TestObject obj1 = new TestObject();\n" +
                "    TestObject obj2 = new TestObject();" +
                "    obj1.add(obj2);" +
                "    insert(obj1);\n" +
                "end";

        String drl1 =

        String javaSrc =
                "package org.kie.test;\n" +
