AopUtils.getTargetClass assumes cglib proxies are always proxying classes [SPR-5694]

[spring-projects-issues]

Iwein Fuld opened SPR-5694 and commented

If you create a cglib proxy for an interface using a third party framework AopUtils will break see INT-654.

Test to demonstrate:

import static org.junit.Assert.assertTrue;
import static org.mockito.Mockito.mock;

import org.junit.Test;
import org.springframework.aop.support.AopUtils;

public class AopUtilsMockitoTests {

	@Test
	@SuppressWarnings("unchecked")
	public void getTargetClass() throws Exception {
		AnInterface candidate = mock(AnInterface.class);
		assertTrue(AnInterface.class.isAssignableFrom(candidate.getClass()));
		assertTrue(AnInterface.class.isAssignableFrom(AopUtils.getTargetClass(candidate)));
	}

	private interface AnInterface {	}
}

This was tested with Mockito 1.7

Affects: 2.5.6
