>             Project: Groovy
>          Issue Type: Bug
>          Components: groovy-runtime
>    Affects Versions: 2.4.4
>            Reporter: Johann
>            Priority: Minor
>              Labels: usability
>
> Given this code:
> {code:java}
> @Lazy
> Foo foo
> abstract class Foo {}
> {code}
> You'll get:
> {code}
> java.lang.InstantiationException
>       at 
> sun.reflect.InstantiationExceptionConstructorAccessorImpl.newInstance(InstantiationExceptionConstructorAccessorImpl.java:48)
>       at java.lang.reflect.Constructor.newInstance(Constructor.java:526)
>       at 
> org.codehaus.groovy.reflection.CachedConstructor.invoke(CachedConstructor.java:80)

> {code}
> This isn't really helpful. If I mistype a method name, Groovy will help me 
> out with suggestions, why not here?
> MODIFICATION by blackdrag:
> @Lazy should recognize this and fail compilation to avoid the initialization 
> of an abstract class.
