Hi all,
I'm writing an RCP application and I intend to use aspects to perform some
common tasks among my application views. The one I'm working on now is
ensuring the thread safety in SWT calls ala [1].

I've implemented a generic SwtThreadSafety aspect with some abstract
pointcuts (to be implemented by specific clients). The first clients for
this aspect are a bunch of application views with receive events and need
to update the UI. So far so good: the right join points are captured and
all works ok.

I want the generic SwtThreadSafety aspect to be part of "ui" java package
while the views (and their ad-hoc aspect) belong to the "ui.views" package.

==== Generic aspect ====

package core.ui;

import org.eclipse.ui.PlatformUI;

public abstract aspect SwtThreadSafety {
// Abstract pointcuts and a few around advices
}

==== Views aspect ====

package ui.views;

// Note that this import is marked as "cannot be resolved" :|
import core.ui.SwtThreadSafety;

public aspect ViewsThreadSafety extends SwtThreadSafety {
// Pointcuts definitition
}

The import is not resolved and SwtThreadSafety is not recognized as a type.
Both files are named with the .aj extension.

If I put both of them in the same package, all works ok.

[Sorry for the dumb question] Where am I wrong? :S

Regards
Mario
