Unhandled exception in the internal of Hippo Repository when delete event workflow configured.

When I configured a workflow event workflow for the 'delete' method, the repository internal code itself prints the following error without proper handling.
Even though the event handling code does not do anything, repository code prints the following stack traces on delete event.
Even if delete event cannot be properly handled for now, this kind of exception must be properly handled in the repository internal codes.
