Description

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:

class TcBug {
    @AnnotationCollector
    @TupleConstructor(defaults = false)
    @interface Collector {}

    @Collector
    @TupleConstructor(defaults = true)
    static class Foo {
        Integer value
    }
}

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.

TcBug.groovy: -1: Unable to compile class com.example.TcBug$Foo due to hash collision in constructors @ line -1, column -1.
