using java lambda function operator (->) in thymeleaf

I am getting Exception evaluating SpringEL expression when using java lambda operator.

example: list.stream().map(a -> a.toString()).reduce("",(a,b) -> a+b)

Define a function similar to the following:

package com.mypackage;
public class CollectorsMap {
    public static final List<String> name(Stream<AbstractName> stream) {
        return stream.map(v->v.getName()).collect(Collectors.toList());
    }
}

invoke it with something similar to the following (values is a list of values):

th:with="valueNames=${T(com.mypackage.CollectorsMap).name(values.stream())}"

This would return the list of name fields of the original list of objects.
