Here's a more complete stack trace:

I've finally been able to reduce this bug to a minimal test case:

--- src/main/java/package1/Abstract.java ---
package package1;

public abstract class Abstract<T> {

	protected Object field;

}

--- src/main/java/bug/package2/Concrete.java ---
package bug.package2;

import package1.Abstract;

public class Concrete extends Abstract<Object> {

	public void method() {
		field = null;
	}

}

--- src/main/aspect/Aspect.aj ---
public aspect Aspect {

	declare error : set(* *) : "";

}

------

See attachment for Eclipse project containing these three source files.

Minimal test case demonstrating the bug

Comment 4 Andrew Clement 2006-11-28 03:54:15 EST

It is related to pipeline compilation - so the files also have to be compiled in a particular order for it to happen, but I've recreated it with those files you attached, thanks!  I have a fix ready to go - but just need to sort out my eclipse credentials so I can commit it...

Comment 5 Andrew Clement 2006-11-29 05:53:42 EST

test and fix committed. thanks for the testcase.

Comment 6 Andrew Clement 2006-11-30 04:06:44 EST

fix available in latest dev build.

Comment 7 Helen Beeken 2006-12-08 09:28:13 EST

This fix is now in the latest AJDT 1.5 dev build (for eclipse 3.3M3)
