Hi,
if I have a class with an enclosed class like this
Class POJO {
private String aField;
...
class AnotherClass {
public void someMethod() {
aField = "something";
}
}
}
and I add an aspect at runtime through these instructions:
AdviceBinding binding = new AdviceBinding("execution(public boolean
Pojo>getCond())", null);
binding.addInterceptor(SimpleAspect.class);
AspectManager.instance().addBinding(binding);
An exception is thrown:
Exception in thread "main" java.lang.NullPointerException

If the field visibility is public the exception is not thrown anymore.
Can someone tell me why?
