NPE in CleaningVerifier / TraitASTTransform #410

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
When I compile this simple code:
@Trait
abstract
class C1 {
    abstract def hello();
    def runHello() { hello() }
}

@Trait
abstract
class C2 {
    abstract def hello();
    def runHello2() { hello() }
}

class C3 implements C1 {
    def hello() { println("Hello1000!")}
}

I get this error:

Even just adding groovypp to classpath without even using @Trait causes the 
same error. People have reported this months ago: 
http://netbeans.org/bugzilla/show_bug.cgi?id=211875

This means that probably NOBODY can use Groovy++ in latest Groovy versions.
I'm using Groovy 2.1.

Is Groovy++ project still active? How such a terrible bug can be unfixed for so 
long?
