[ https://issues.jboss.org/browse/DROOLS-509?page=com.atlassian.jira.plugin... ] Mario Fusco commented on DROOLS-509: ------------------------------------ I tried to reproduce this problem with the following test case also switching the MvelConstraint.TEST_JITTING flag to true but it works for me and I couldn't generate any CCE. Am I missing something? {code} public interface I0 { String getValue(); } public interface I1 extends I0 { } public static class X implements I1 { @Override public String getValue() { return "x"; } } public static class Y implements I1 { @Override public String getValue() { return "y"; } } @Test public void testMethodResolution() throws Exception { // DROOLS-509 String drl = "import " + I1.class.getCanonicalName() + ";\n" + "rule R when\n" + " I1 ( value == \"x\" )\n" + "then\n" + "end"; KieHelper helper = new KieHelper(); helper.addContent( drl, ResourceType.DRL ); KieSession ksession = helper.build().newKieSession(); ksession.insert(new X()); ksession.fireAllRules(); ksession.insert(new Y()); ksession.fireAllRules(); } {code} -- This message was sent by Atlassian JIRA (v6.2.6#6264)
