Description

Cannot compile this code in 2.3.0.

import groovy.transform.CompileStatic

@CompileStatic
class ForInTest {
    static interface List2<E> extends List<E> {}
    static class ArrayList2<E> extends ArrayList<E> implements List2<E> {}
    static List2 list = new ArrayList2()

    static void main(String[] args) {
        for (def e in list) {}
    }
}

The error message is this.

Line 10, expecting casting to java.util.Iterator <E extends java.lang.Object> but operand stack is empty

Maybe this problem is related to GROOVY-6791
