Infinite loop for pattern to execute SUN-FRI

[rudivk]

I recently changed my cron pattern from "0 15 0 ? * MON-FRI *" to "0 15 0 ? * SUN-FRI *".
I tried the syntax with https://www.freeformatter.com/cron-expression-generator-quartz.html and that seemed to work fine.
However, when my felix server is starting up and passes the cron pattern onto enroute, the startup thread seems to be blocked (infinite loop) while parsing the pattern.

Is this a bug on your end or should I be using another pattern to execute my job at 00:15 except on all days of the week except Saturday?

For completeness' and clarity's sake, I thought I'dd add the stacktrace:
