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

> def errMsg = shouldFail '''
> @groovy.transform.CompileStatic

> 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>]')
