Thymeleaf's layout:fragment not working after packaged in jar

So, I am writing a Spring boot app with Thymeleaf as my template engine. When I run my project through Spring Tool Suite, everything works as it should.

However, when i run mvn clean package and run jar that is generated, my layout:fragment stops working, saying it cannot resolve it:

org.thymeleaf.exceptions.TemplateInputException: Error resolving template "Layout", template might not exist or might no t be accessible by any of the configured Template Resolvers (index)

My layout.html:

<!DOCTYPE html>
<html xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout" xmlns:th="http://www.thymeleaf.org">

    <head>
        <title layout:title-pattern="$DECORATOR_TITLE - $CONTENT_TITLE" >my Site</title>
        <meta charset="UTF-8"/>
    </head>
    <body onload="init()">
        <header>
            <nav class="navbar navbar-inverse">
                <!-- Navigation bar -->
            </nav>
        </header>
        <section layout:fragment="vsebina" style="padding: 25px;"></section>
    </body>
</html>

and my index.html:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" 
        xmlns:th="http://www.thymeleaf.org" 
        xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
        layout:decorate="~{layout}"
        layout:decorator="Layout">

    <head>
        <title>Index</title>
    </head>
    <body>
        <section layout:fragment="vsebina">
            ...
            Content of my index page
            ...
        </section>
    </body>
</html>

and my pom.xml

                </configuration>
            </plugin>
        </plugins>
    </build>


</project>

It seems odd that in one case it works and in another it doesn't. Or am I doing something wrong?

Apparently the problem was in html tag:

<html xmlns="http://www.w3.org/1999/xhtml" 
        xmlns:th="http://www.thymeleaf.org" 
        xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
        layout:decorate="~{layout}"
        layout:decorator="Layout">

This was needed to change into this:

<html xmlns="http://www.w3.org/1999/xhtml" 
        xmlns:th="http://www.thymeleaf.org" 
        xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
        layout:decorate="~{layout}"
        layout:decorator="layout">

layout:decorator="Layout" to layout:decorator="layout"

In Spring Tool Suite the capital L didn't caused problems, but when the app was packaged into jar, it started to cause problems.
