We have a job that creates and archives a python virtual environment, which includes multiple symbolic links. For example:

lrwxrwxrwx 1 jenkins jenkins 30 Jun 27 17:40 UserDict.py -> /usr/lib/python2.7/UserDict.py

The downstream job then tries to copy the artifacts from the upstream job, but fails as follows:

java.io.FileNotFoundException: /var/lib/jenkins/jobs/.../builds/384/archive/venv/lib/python2.7/UserDict.py

This started happening on multiple pre-existing jobs that were working just fine prior to an upgrade of the copyartifact plugin from 1.38.1 to 1.40. Rolling that plugin version back to 1.39.1 fixed the issue.
