Re: [aspectj-users] Before I forget

Hi Andy.

This is an odd one. I only saw it the one time so I don't know how deep we can delve into it, but at the time I was editing a class that is not itself generic nor does it have any generic types in its hierarchy (I know, seems to be a first). It's possible that the update caused another class to be recompiled which resulted in the error, but without any more information from the stack trace I can't guess which one it was. If you have anything else you'd like me to check out I'd be willing to dig deeper, otherwise I'll let you know if it pops up again.

The exception would appear to occur for an ITD on a generic type where
the ITD is sharing a type variable with the target.
It is attempting to identify the actual occurrence of parameterization
in the target type so it knows what the type variable should bind to.

If the ITD is

List<Z> SomeInterface<Z>.foo;

and the generic declaration is

class Clazz implements SomeInterface<String> {

then it is looking for SomeInterface in the Clazz hierarchy - so it
knows Z is String for the new member in Clazz.  For some reason it
doesn't find SomeInterface in the Clazz hierarchy (is it perhaps being
declare'd parents'd in? that would be pretty advanced)

The exception is thrown with some text to give us more information, I
wonder why you don't see it...

Just had this pop up in Eclipse while doing some refactoring today:

Version: 2.0.1.e35x-20091001-1600
I don't expect that it will be a continual problem, but thought you'd like
to take a look into the cause.
I've also noticed that incremental compilation often seems to not update the
markers in the IDE until I've done a full rebuild. Several times I've
deployed code from a project with no markers only to have it fail with an
exception when running that is equivalent to what the build error was.
After a clean/rebuild the appropriate error shows up in Eclipse. Any
recommended steps for debugging that?
