The other I spent 3 hours trying to fix the following error and I couldn't find the answer here, so now that I've found the answer I've decided to share it with you.
I'm working with Java 6, Spring MVC, JAXB and while I was creating a new webservice, I got this error:

i'm trying to check if my list called listPersons is empty or not, but when i check i got an error like this:
Caused by: org.attoparser.ParseException: Exception evaluating
SpringEL expression: .... Caused by:
org.thymeleaf.exceptions.TemplateProcessingException: Exception
evaluating SpringEL expression: "#lists.isEmpty(listPersons"
(template: "index" - line 15, col 8)
I have tried this:
<h2 th:if="${#lists.isEmpty(listPersons)}">No hay personas</h2>
<div th:if="${#!lists.isEmpty(listPersons)}">
and this:
${listPersons.isEmpty()}
But none of the options are working. I'm using thymeleaf-3.0.15 and springboot version 2.7.2
In my Java method i have this line:
model.addAttribute("listPersons", personaService.getAll());
You are not using the conditional statements correctly, hence you are getting the SPEL error
<div th:if="${#!lists.isEmpty(listPersons)}">
Use the below for your condition
<div th:if="${not #lists.isEmpty(listPersons)}">
Refer https://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#conditional-evaluation
to get more insights.

Actually it was the jar issue.In code i was using rest-client jar 1.0.4 and my spring xd version was 1.3.1.
Moreover latest rest-client jar(1.3.1) is not available in maven but the same is available in deployment folder of spring-xd.
https://mvnrepository.com/artifact/org.springframework.xd/spring-xd-rest-client
