Grails 7.0.x with Tomcat 11 layout <meta name="layout" content="main" /> is not working

[sbal5488]

Grails 7.0.x with Tomcat 10 is working superb but the same webapp with Tomcat 11 is not working.
No Errors either on the console or in the logs.

Any help on this appreciated.

Grails 7.0.x uses Spring Boot 3.4.x which supports tomcat 10.1.x. You can see the supported versions on https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-dependencies/3.4.3 or on https://mvnrepository.com/artifact/org.grails/grails-bom/7.0.0-M1.

spring-projects/spring-boot#42730 (comment) - Tomcat 11 support might be added in Spring Boot 3.5.x, which will become Grails 7.1.x.

Spring Boot 3.4.x supports Tomcat 11.0.4, The URL which you gave states that.
We are using Spring Boot 3.4.x with Tomcat 11 container for some of our Java related Apps. We don't see any problems with that.

Even Grails App is good. Most of the features are working as expected, except layout.

The below gsp, if i remove meta tag, then am able to render the page, but if i include the meta tag, am getting a blank page. No errors on the logs or screen or developer tools

<title>MyTitle</title> **** This is my content!

I guess some problem on the sitemesh side, but am not sure.
If you can give me a workaround to get rid of this problem, that would be great. Otherwise am blocked.

Can you share a link where Spring states that Spring Boot 3.4.x supports Tomcat 11? I am only seeing it might be supported in Spring Boot 3.5.x, which will be released in May 2025 and that it will be supported in Spring Boot 4.0.x which will be released in Nov 2025.

And report the sitemesh issue with Tomcat 11 on https://github.com/grails/grails-gsp/issues, which includes the grails-sitemesh plugin, with a basic example.

Sitemesh 3.2.x which is used by the grails-sitemesh plugin supports Jakarta EE 10 according to https://github.com/sitemesh/sitemesh3?tab=readme-ov-file#get-up-and-running-with-a-single-jar-no-configuration-needed-just-drop-it-in.

Tomcat 11 is Jakarta EE 11

Grails 7.0.x has been tested with Tomcat 10.1.x up to this point.
