Re: [aspectj-users] Problem compiling J2SE 5.0 source with ajc

[Andrew Clement <CLEMAS@xxxxxxxxxx>]

Unfortunately, no, if the annotation
has source retention then it isnt in the RuntimeVisibleAnnotation or RuntimeInvisibleAnnotation
attributes in the class file - and its the class file we weave.

As a rule we don't have join points
for anything that doesn't exist in the class file.  Besides this case,
the other well known example is that you can't put after advice on a handler
join point because the end of a catch block isn't reliably identifiable
in the class file when its obvious in the source.  We have this rule
so the semantics of weaving are the same regardless of whether you pass
source or binary inputs to the weaver.

cheers,
Andy.

p.s. Adrian did start looking at the
new compiler on schedule :)

I see an interesting question here: can AJ work on annotations with retention
type set on source? Is
this present inside the bytecode as to allow ajc in the 2nd step to take
the necessary actions?
