Description

Original:
While testing the fix that [~jglick] has provided for git plugin 4.0 and git plugin 3.10, I found a null pointer exception that I need to investigate further when using JGit as the git implementation. The stack trace was:

The failure seemed to be intermittent and limited to the JGit implementation. It was not visible in the command line git implementation.
