Warning seen when saving a maven project in Jenkins when Git as source code management is used

I am new to Jenkins and creating a maven job.
Jenkins is installed/deployed in CentOS.

App versions:
Jenkins: 2.401.1
Java: OpenJDK 17
Maven: 3.8.1
Git: 1.8.3.1

When 'Git' is used as Source Code Management, saving the job shows 'A problem occurred while processing the request.' in UI.

At logs, following is logged:

When the same job is opened after reload, the settings made can be seen. However, if any changes are made and saved again- above is seen.

I am trying resolve the error/warning seen, but haven't found any solution for this.
It would be great to get some solution for this.

The error is not seen when Java 11 is used.
