      Description

      Hello, everybody,
      I have a problem with the slack plugin. After the installation and configuration it went quite well for a few days with the slack plugin.

      In between nothing was changed neither at the Jenkins nor at the system. Today I noticed however that I come on almost no Admin sides more.

      Among them "Globale security configuration" "Credentials configuration" and "Configurations of the utilities" the plugin always ejected the following stack trace:
