Forked container "no security manager: RMI class loader disabled" when remote container can not inject a service [PAXEXAM-493]

[ops4j-issues]

Christoph Läubrich created PAXEXAM-493

Consider the following test case:

@RunWith(PaxExam.class)
@ExamReactorStrategy(PerClass.class)
public class RemoteFailingTest {

    @Inject
    Runnable runnable;

    @Configuration
    public Option[] config() throws IOException {
        return options(junitBundles());
    }

    @Test
    public void myTest() {
        System.out.println("Called!");
    }
}

This fails with a "service not found in time" in the native container (as intended here) but fails with

in the forked container (if the service is present it runs fine).

When searching for this the policy file is mentioned, but it does not seem to help tp specify one. I have tested this on a 3.1.0 but maybe other versions are affected as well.

Can't reproduce on 3.0.x branch, see new test
itest/osgi/src/it/regression-multi/src/test/java/org/ops4j/pax/exam/regression/multi/depend/MissingServiceInvokerTest.java

Rescheduled to 3.1.0, needs to be tested on master.

Cristoph,

I am curious - Are you using Equinox? I ask because I am seeing "no security manager: RMI class loader disabled" errors with Equinox that I don't see with Felix. I am seeing them in a different product though (activemq web console).

[ops4j-issues]

Christoph Läubrich commented

Yes, I'm using equinox (3.7) and running the test directly from within eclipse without using maven.

G commented

How are you testing in Eclipse (PDE or Bndtools)? Can you drop back to equinox 3.6 (I didn't have a problem with Equinox 3.6) or try Felix instead? If you have the same experience as me, then it is some change in Equinox 3.7 and onwards causing the problem.

If it is an equinox problem I am surprised that I haven't seen more people reporting the same issue.

I'm using PDE, I might try this next time the error occurs.

it might because

• ppl using felix when using exam maybe
• it only happens when your setup is "wrong" (missing dependecy) and most ppl will setup it correctly :smile:
• it only happens on forked container

I know another (not exam related) project also has issues when it comes to RMI and they are using a special policy file to circuvent this together with eclipse. I personally try to avoid the RMI stuff whenever possible :smile:

I had the same issue on Equinox 3.6 (using the Karaf Pax Exam container).

Moving to "unscheduled" - don't see how to progress unless someone comes up with a minimal self-contained test to reproduce the problem.
