Aspect perthis clause error

[Jean-Louis.Pasturel-2]

I try to write a simple abstract LTW aspect with the perthis clause  
using  the concrete-aspect mecanism :

My aspect :

/package jlp.aspectsJMX.abstractAspects;
public abstract aspect AbstractCPUDurationSimpleMethodPerthis
perthis(methods())  {
   
    public abstract pointcut methods();

    Object around(): methods()     {
        System.out.println("Execution around");
    return proceed();

    }

}
/
my aop.xml file
/<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<aspectj>
    <aspects>
     <concrete-aspect
extends="jlp.aspectsJMX.abstractAspects.AbstractCPUDurationSimpleMethodPerthis"
                                           
name="jlp.aspectsJMX.abstractAspects.AbstractCPUDurationSimpleMethodPerthisImpl">
            <pointcut expression="execution(public *
SessionExample.doPost(..))" name="methods"/>
        </concrete-aspect>


</aspects>
<!-- Foot Mode Verbose -->

   
    <weaver options="-XnoInline -Xlint:ignore -verbose -showWeaveInfo  
-Xset:weaveJavaPackages=true,weaveJavaxPackages=true,typeDemotion=true">
        <exclude within="iep.perf..*"/>
        <exclude within="jlp.aspectsJMX..*"/>
        <exclude within="org.hibernate.type.ComponentType"/>
        <exclude within="*..*EnhancerByCGLIB*..*"/>
        <exclude within="*..*.*$$EnhancerByCGLIB$$*"/>
        <exclude within="*..*.*$$EnhancerByCGLIB$$*"/>
        <exclude within="*..*.*$$FastClassByCGLIB$$*"/>
    </weaver>
</aspectj>
/
A simple application ( servlets-examples of Tomcat 5.5.28)
SessionExample.java ( a servlet, i try to weave the doPost method)

I get the exception below :

is it a bug ? a default aspect ( issingleton ) runs correctly.

Hi,

Yes that is a bug I think - we shouldn't be creating that interface
again (and causing the duplicate class problem).

cheers,
Andy
