[aspectj-users] weaver has problems with serializable generics

[Peter Panec <peter.panec@xxxxxxxxxxxxx>]

The weaver throws an IllegalStateException when I have a generic type 
that implements Serializable. An example would be:

  public class MyList<E> implements List<E>, Serializable
   {
      ...
   }

The problem occurs when the weaver is handling an advice of the form:

   @AfterReturning(pointcut="execution(public List 
com.mitratech.*.get*())", returning="rlist")
   public void afterReturningListMethod (List rlist)
   {
       //do something or nothing
   }

The weaver throws the following error:

abort ABORT -- (IllegalStateException) Can't ask to parameterize a 
member of non-generic type: com.mitratech.MyList  kind(raw)
Can't ask to parameterize a member of non-generic type: 
com.mitratech.MyList  kind(raw)
java.lang.IllegalStateException: Can't ask to parameterize a member of 
non-generic type: com.mitratech.MyList  kind(raw)

I'm wondering if there is a bug here. The reason I say this is that I 
tried in on the Java source code for generic collections. Sure enough, 
the weaver had problems with the Java generic ArrayList. Note the 
problem only occurs when I run it on the source code; the weaver does 
not have problems with the compiled ArrayList in rt.jar.

I have pinpointed the problem to the presence of the Serializable 
interface in the implements clause. If I remove Serializable from the 
declaration of MyList above, as well as from the Java ArrayList class, 
the weaver is happy.

I tried using Externalizable instead of Serializable, but to no avail. I 
really need my class to be serialized and I can't think of any 
workaround. Any help on this matter would be appreciated.

Thanks.
