FailingSerializer (jackson-databind 2.16.1)

java.lang.Object
- com.fasterxml.jackson.databind.JsonSerializer<T>
- - com.fasterxml.jackson.databind.ser.std.StdSerializer<Object>
  - - com.fasterxml.jackson.databind.ser.impl.FailingSerializer

All Implemented Interfaces:

JsonFormatVisitable, SchemaAware, Serializable
```
public class FailingSerializer
extends StdSerializer<Object>
```
Special bogus "serializer" that will throw JsonMappingException if its serialize(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator, com.fasterxml.jackson.databind.SerializerProvider) gets invoked. Most commonly registered as handler for unknown types, as well as for catching unintended usage (like trying to use null as Map/Object key).
