We get a exception after update to version 1.0.29:

05.04.2019 12:03:45  error hudson.AbortException: Unable to retrieve object names: selector(...); action failed: {reference={}, err=error: unable to read certificate-authority E:\Jenkins\workspace\java-test-new@2\serverca1793125836374139703.crt for oscp-api-lan-test-lan-huk-coburg-de:8443 due to open E:\Jenkins\workspace\java-test-new@2\serverca1793125836374139703.crt: Das System kann die angegebene Datei nicht finden.

After switch back to version 1.0.28 , it works.

We think, this code commit change is the problem:
