Simulation fails for multiple instances working an activity with a timetable entry ending on Monday 00:00:00

[MaximilianKoenig]

Input

A Scylla configuration with the following properties:

• A role whose timetable includes an entry ending on "Monday 00:00:00" in the global configuration
• At least one activity requiring at least two instances of the same role for its execution

Example model and configuration: Scylla_Bug_Config.zip

Expected behavior

The simulation runs through without error, as is the case if either of the above properties is not fulfilled, e.g., "Monday 00:00:01" as end date or no activity requiring multiple instance of the role.

Observed behavior

The simulation fails immediately upon encountering an instance of the activity requiring multiple instances of the specified role, throwing a NullPointerException.
