I don't know where the screenshot is coming from, nor the problem you're trying to report. If you're looking for support, please ask on StackOverflow with more details. If this is a problem with a tool, this is the wrong place to report this.

@leshalv I believe, this is a bug, that leads to a memory leak: https://github.com/spring-projects/spring-session/issues/1987.

I provided description and PR for fix.
