could you please elaborate the changes?

It is just moving the folder into the common folder used by spring boot for jsp.
I didn't see any side effect of the changes.

i just question this claim about common/default folder by spring boot, because i did not encounter such a thing in my experience.

As I understand it:

• When using JSP with Spring Boot, a WAR package is required, which in turn relies on the maven-war-plugin. (https://docs.spring.io/spring-boot/reference/web/servlet.html#web.servlet.embedded-container.jsp-limitations)
• The default warSourceDirectory for this plugin is src/main/webapp, and this value is not overridden by spring-boot-starter-parent (https://maven.apache.org/plugins/maven-war-plugin/war-mojo.html#warSourceDirectory)
