Trying a very simple aspect just to try to isolate another problem...

Class----------------------------
package blah;

import java.util.Random;

public class MyClass {
	public Integer getRandomInt()
	{
		return new Integer(new Random().nextInt());
	}
}
---------------------------------

Aspect---------------------------
package blah;

public aspect MyAspect {

	pointcut callPointCut(): call(public * blah.MyClass+.*(..));
	
	Object around() : callPointCut() {
		System.out.println("start of around");
		Object result = proceed();
		System.out.println("end of around");
		return result;
	}
}
------------------------------

Gives the following.

ClassCastException thrown: null
Comment 1 Andrew Clement CLA 2005-12-01 05:52:05 EST 
Hmmm ... those compile fine for me.  Does it happen when you do a full build or only when you do an incremental build of the project containing these files? (An incremental build occurs when you change a file slightly and press Ctrl+S to save, whilst a full build occurs when you press the AJ build button on the toolbar).
Comment 2 Ian Orford CLA 2005-12-01 06:07:10 EST 
Incremental only.
In fact, now I've done a proper build, even incremental builds are working.

It may still be a bug, but I'm sorted.

Presumed fixed as unable-to-reproduce.  Please reopen if reproduced.
