Description Ron Bodkin 2005-11-18 17:35:01 EST

The following aspect is flagged as an @AspectJ aspect by the compiler which 
causes it to throw an NPE when loading it with load-time weaving. This is 
simplified from the original code that triggered this bug (an aspect with some 
methods, fields, and pointcuts but no advice or ITD's...) I will also attach 
the bytecode produced by ajc in Java 1.5 source compilation mode for this.

package com.crankj.aspects;

public aspect TestBadAtaj {
//


}

Here’s the stack trace:
