Jackson Deserialize failure with 15.1.1 -> 15.1.2 upgrade

[AndrewWestberg]

After upgrading to 15.1.1 -> 15.1.2, Jackson is not able to deserialize the Schedule type.

Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `com.github.kagkarlsson.scheduler.task.schedule.Schedule` (no Creators, like default constructor, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information
 at [Source: REDACTED (`StreamReadFeature.INCLUDE_SOURCE_IN_LOCATION` disabled); line: 1, column: 13] (through reference chain: com.github.kagkarlsson.scheduler.task.helper.PlainScheduleAndData["schedule"])

I cannot see what would have caused that 🤔

Though I can see that that type is not very Jackson-friendly..
