Following this checklist to help us incorporate your contribution quickly and easily:

• Make sure there is a GitHub issue filed
  for the change (usually before you start working on it). Trivial changes like typos do not
  require a GitHub issue. Your pull request should address just this issue, without pulling in other changes.
• Each commit in the pull request should have a meaningful subject line and body.
• Format the pull request title like [#XXX] - Fixes bug in SessionManager,
  where you replace #XXX with the appropriate GitHub issue. Best practice
  is to use the GitHub issue title in the pull request title and in the first line of the commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• add fixes #XXX if merging the PR should close a related issue.
• Run mvn verify to make sure basic checks pass. A more thorough check will be performed on your pull request automatically.
• If you have a group of commits related to the same change, please squash your commits into one and force push your branch using git rebase -i.
• Committers: Make sure a milestone is set on the PR

Trivial changes like typos do not require a GitHub issue (javadoc, comments...).
In this case, just format the pull request title like [DOC] - Add javadoc in SessionManager.

Great, thanks
Now the only thing we need for our Spring / SpringBoot community to verify the fix.
