Description

Nested generics should be shown as well, see the TODO in the following code:

class Groovy8609Bug extends CompilableTestSupport {
    void testUpperBoundWithGenericsThroughWrongType2() {
        def errMsg = shouldFail '''
        @groovy.transform.CompileStatic
        public class A<T extends List<E>, E extends Map<String, Integer>> {
            E getFirstRecord(T recordList) {
                return recordList.get(0)
            }
            
            static void main(args) {
                def list = new ArrayList<HashMap<String, Long>>()
                def record = new HashMap<String, Long>()
                list.add(record)
                def a = new A<ArrayList<HashMap<String, Integer>>, HashMap<String, Integer>>()
                assert record.is(a.getFirstRecord(list))
            }
        }
        '''

        // TODO we should print generics details, e.g. [Static type checking] - Cannot call A <ArrayList, HashMap<String, Integer>>#getFirstRecord(T) with arguments [java.util.ArrayList <HashMap<String, Long>>]
        assert errMsg.contains('[Static type checking] - Cannot call A <ArrayList, HashMap>#getFirstRecord(T) with arguments [java.util.ArrayList <HashMap>]')
    }
}
