      After updating all plugins for our Jenkins installation (2.361.3) and removing the "Pipeline: Deprecated Groovy Libraries" plugin, we noticed that the plugin started to throw a NPE once a multibranch pipeline received a webhook.

      The result is, that the pipeline job was still triggered ending up in several endless loops.
