When using Jenkins inside Amazon EC cloud (and using Amazon Code Commit git provider), the attached stack trace was observed while trying to modify and save the build project settings. The crash is relevant to hudson.plugins.git.GitSCM.

The project uses git to fetch the sources. This initially worked, and the project actually even runs the build no problem, but it cannot be modified because of the crash. Strange to see the Git plugin crash on action that itself should not include any interaction with repository.

Using Jenkins 2.164.3.
