Upgrading TFS Plugin from version 4.0.0 to 4.1.0 make system unusable.

Tried creating a new job from scratch and same error occurs. Workaround is to revert to V4.0.0. This is reproduced on 2 different linux jenkins instances, with Windows clients.
V 4.1.0 does not have the issue on a newly installed Windows installation jenkins 1.642.2.

The following error occurs when the TFS plugin tries to connect to TFS(poll, checkout):
