Hi @marcusdacoregio,

Commits squashed with updated message.

Regarding checkstyle, running ./gradlew format checkstyleMain returns the following error for me:

Reason: Task ':spring-session-core:compileJava' uses this output of task ':spring-session-core:formatMain' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.

If I add:

tasks.named("formatMain") {
    dependsOn(tasks.named("compileJava"))
    dependsOn(tasks.named("checkstyleMain"))
}

to each modules build.gradle, this allows ./gradlew format checkstyleMain to run but returns success with no issues.

Running ./gradlew format checkstyleMain on the main branch with the above gradle task changes shows the style issues exist in spring-session-core DefaultCookieSerializer.java.
