Description

```java
ParameterExpression parameter = criteriaBuilder.parameter(List.class, "list");
```
is not type safe, We need add a *Super Type Token* like [TypeReference](https://github.com/FasterXML/jackson-core/blob/514d9c89b9abab426ed4057806e7a99f6c1f7a58/src/main/java/com/fasterxml/jackson/core/type/TypeReference.java)
```java
ParameterExpression> parameter = criteriaBuilder.parameter(new TypeReference>{}, "list");
```

Research direction

Start by reviewing the CriteriaBuilder parameter API and the linked Jackson TypeReference example to understand the requested generic type representation. Determine the compatible API shape and add coverage for the List example; done means criteria parameters can preserve that generic type safely.
