ajc is directing you to one of its limitations: it can't
implement around advice on {pre-}initialization join points.
(If/since this is the case, we should document it in the
semantics appendix of the Programming Guide, as the
handler case is.)

If you don't know why it's picking out those join points,
most likely you have a pointcut that picks out a bunch of
join points for your around advice, e.g.,

   Object around() : within(MyClass) {
      System.out.println("start!" + thisJoinPoint);
      try {
	return proceed();
      } finally {
          System.out.println("end!" + thisJoinPoint);
      }
   }

You can exclude {pre-}initialization and handler join points
as follows:

   Object around() : within(MyClass)
          && !initialization(MyClass.new(..))
          && !preinitialization(MyClass.new(..))
          && !handler(*) {
       ...

Or you can re-write the pointcut to pick out other kinds
of join points.

Thanks for bringing this up -

Hi All,

I just started using AspectJ a week ago...tried out all the example.

When I try to use it in my project using iajc with ant, my ant setting is:

<target name="compilej" depends="resources,init">
  <iajc destdir="${build}"
	failonerror="off"
	argfiles="${mjaopSrc}/dev.lst"
	proceedonerror="on"
	verbose="off">
	<srcdir>
	  <pathelement path="${mjfSrc}" />
	  <pathelement path="${mjappSrc}" />
	</srcdir>
	<classpath>
	  <fileset dir="${build.classpath}" >
	    <include name="**/*.jar" />
	    <include name="**/*.zip" />
	  </fileset>
	</classpath>
  </iajc>
 </target>


I got a bunch of errors:
D:\Projects\mj\src\mjaop\com\mediajunkies\aspect\dev\Test.java:25 around on initialization not supported (compiler limitation) D:\Projects\mj\src\mjaop\com\mediajunkies\aspect\dev\Test.java:19 around on initialization not supported (compiler limitation)

D:\Projects\mj\src\mjf\com\mediajunkies\appkit\dnd\datatransfer\EOGlobalKey.java
:7 around on initialization not supported (compiler limitation)
...

Am I missing something?

Thanks
