Having jsp, which uses implicit jsp variable, such as out in lambda expression [1] fails to compile, see [2]. Using instead of lambda's forEach standard for cycle works without issues.

test.jsp using lambda with implicit variable
<%@ page language="java" pageEncoding="UTF-8" contentType="text/plain;charset=utf-8"%> <% String[] names = {"Joe", "Doe", "John", "Peter"}; java.util.List<String> namesAsList = java.util.Arrays.asList(names); namesAsList.forEach(out::println); for (String name : namesAsList) { out.println(name); } %>
