Issue 410 in groovypptest: NPE in CleaningVerifier / TraitASTTransform

New issue 410 by iir...@gmail.com: NPE in CleaningVerifier /
TraitASTTransform
http://code.google.com/p/groovypptest/issues/detail?id=410

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?

Alex no longer works on groovy++.  Try kotlin
