The best way for me is define a modal div which in default have a display none property. Then you can display with position fixed or position absolute depen you needs:

If you want to cover all screen, your modal position is fixed and you can put div anywhere of your code.

Else if you only want to cover one zone, put your modal into the div which you want to cover and put the parent div with position relative.

As per your code, There are so many syntax errors in single and double quotes where you append the html. Please check below code without any syntax error.

This is a potential answer. I haven't been able to reproduce the issue.

When you invoke new ClassPathResource using Spring, you are setting no class loader. I supposed that Spring used the System classloader (ClassLoader.getSystemClassLoader()).

Wrong. Spring uses an internal utility method to get the class loader of the current context, bound to the thread. It could have happened, for reasons unknown to me, that the class loader bound to the bean initialization method (which happened to be a WebApplicationClassLoader sponsored by Apache Tomcat) is not the same as the system class loader.

The Oracle system class loader, in fact, is unable to load resources from Jar files. At least because I have debugged and found the answer by myself.

Maybe, and I say maybe, removing parallelism and not saving 2 seconds of one-time startup processing, makes the Lambda expression able to get the web application classloader instance instead of the Oracle JDK.

This, however, does not explain why this happened only at customer site and not in all of our environments, PROD included.

Solution 2 is to explicitly pass getClass().getClassLoader() to constructor of ClassPathResource
