Groovy mistakenly using constructor of enclosing class?

问题

Given:

static class Question {
    // stuff
    List<Value> values

    static class Value {
        // stuff
    }

When I run:

Question question = new Question()
question.id = "whatever"

if (it == QuestionType.SELECT || it == QuestionType.MULTICHOICE) {
    question.values = [new Question.Value(), new Question.Value()]

    for (Question.Value v : question.values) {
        // stuff
    }

question.values contains an array of Question objects and NOT Value.

Intellij doesn't give me any error nor warnings. I tried evaluating "new Question.Value()" during debug and it correctly constructed a Value object.

However, if I use a static import:

import static <path>.Question.*

And thus transforming the if content to:

question.values = [new Value(), new Value()]

for (Value v : question.values) {
    // stuff
}

Then I correctly get an array of Value objects!

It doesn't make any sense to me... can anybody enlighten me, please?
