RE: [aspectwerkz-user] Weaving private methods

Hi Alexandre,
Indeed I am trying to weave constructors.  Intesting you don't hit this though.  I note that you recommend the JRockit compiler/vm for running aspectwerkz and weblogic together.  Maybe this is the source of my problem?

I am using aspectwerkz 2.0 final, so I guess it's not that.

Best wishes,
Graham.

private member interception is supported

From what you post here, I can imagine you have an advice on a
constructor call, for a class that would instantiate an instance of
himself in the static initialiezer ie like below and I don't have the
problem you have.

Are you using 2.0 final ? Can you reproduce it ?
Alex


package test.priv.sub;
public class PrivateTarget {
    public static PrivateTarget s_singleton = new PrivateTarget(1);

    private PrivateTarget(int i) {
        int j = i;
    }

}

I could weave that with:

package test.priv;
public class PrivateCtorTest extends TestCase {

    public void testPrivateCtorCall() {
        PrivateTarget i = PrivateTarget.s_singleton;
        assertTrue(i!=null);
    }

    public static class TestAspect {

        @Before("within(test.priv.sub.PrivateTarget) && call(*.new(..))")
        public void before() {
            int i = 0;
        }
    }

    public static void main(String[] args) {
        junit.textui.TestRunner.run(suite());
    }

    public static junit.framework.Test suite() {
        return new junit.framework.TestSuite(PrivateCtorTest.class);
    }
}
