RE: [aspectwerkz-user] Weaving private methods

Hi,

Thought maybe not using JRockit was the source of my problem, but it turns out not to be so.

I've reduced my aspect down to just empty stub methods.  The aspect does nothing and imports nothing except org.codehaus.aspectwerkz.joinpoint.StaticJoinPoint.

And yet when I start weblogic, I get the following:
The WebLogic Server did not start up properly.
Exception raised:
java.lang.IllegalAccessError: <init>
        at weblogic.security.providers.authorization.DefaultAuthorizationUtils_4_1187989080_369379917__92347188___AW_JoinPoint.invoke(Ljava.lang.String;Ljava.lang.String;Lweblogic.security.providers.authorization.DefaultAuthorizationUtils;)Lweblogic.security.providers.authorization.DefaultAuthorizationUtils;(Unknown Source)
<snip>

I wonder if there's a problem with my startup line?

My aop.xml script looks like this:
<aspectwerkz>
    <system id="MyAspects">
        <package name="com.utils.debug">
            <aspect class="ObjectLifecycleTracker">
                <pointcut name="construction" expression="call(java.lang.Object+.new(..)) and !within(com.utils.debug.ObjectLifecycleTracker*)"/>
                <advice name="beforeConstruction" type="before" bind-to="construction"/>

                <pointcut name="deletion" expression="call(* java.lang.Object+.finalize()) and !within(com.utils.debug.ObjectLifecycleTracker*)"/>
                <advice name="afterDeletion" type="after" bind-to="deletion"/>
            </aspect>
        </package>
    </system>
</aspectwerkz>

Sorry for the verbose post.

Do you spot anything glaring?  How does access to private methods work in aspectwerkz?
Best wishes,
Graham Bygrave.

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);
    }
}
