NullPointerException when @NonNull is used in abstract method #559

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Use @NonNull in abstract method:

import lombok.NonNull;

public abstract class Example {
    public abstract void get(@NonNull String a);
}

2. Compile using javac

What is the expected output? What do you see instead?
