Just recently started seeing this when I attempt to edit projects. This thing is when I go into edit the configuration the git portion updates itself automatically briefly displaying some red text and then resetting one of my git entries in my project. I've tried clearing the wildcards in my entries and saving but it still won't apply and gives the same stack trace every time.

I verified I was running the latest plugins and LTS version to make sure it wasn't a bug in older software.

When I set everything back to how it was and hit save or if I just hit apply with making no changes I get this exception error.

I tried reverting to an older build version in case some change made to the entry caused this but it continues to occur even if I revert to an older version.

A problem occurred while processing the request. Please check our bug tracker to see if a similar problem has already been reported. If it is already reported, please vote and put a comment on it to let us gauge the impact of the problem. If you think this is a new issue, please file a new issue. When you file an issue, make sure to add the entire stack trace, along with the version of Jenkins and relevant plugins. The users list might be also useful in understanding what has happened.
