> Collected TupleConstructor causes internal compiler error

> Key: GROOVY-10789
> URL: https://issues.apache.org/jira/browse/GROOVY-10789
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 4.0.5
> Reporter: Christopher Smith
> Assignee: Eric Milles
> Priority: Major
> Fix For: 4.0.7
>
>
> I have an in-house annotation collector that applies some of the usual
> transforms (TupleConstructor, ToString, CompileStatic/POJO). There's a
> particular class where I want a no-arg constructor available, and I expected
> that I could "override" the annotation's values like this:
> {code:groovy}
> class TcBug {
> @AnnotationCollector
> @TupleConstructor(defaults = false)
> @interface Collector {}
> @Collector
> @TupleConstructor(defaults = true)
> static class Foo {
> Integer value
> }
> }
> {code}
> However, this results in the following error message. I had thought that the
> above would work; if it isn't "supposed to", then a clearer error message
> (with location) would be helpful.
> {code}
> TcBug.groovy: -1: Unable to compile class com.example.TcBug$Foo due to hash
> collision in constructors @ line -1, column -1.
> {code}
