DEFAULT_UNTOUCHABLES

protected static final HashSet<ClassKey> DEFAULT_UNTOUCHABLES

Looks like we need to worry about accidental data binding for types we shouldn't be handling. This is probably not a very good way to do it, but let's start by blacklisting things we are not to handle.

(why ClassKey? since plain old Class has no hashCode() defined, lookups are painfully slow)

DEFAULT_UNREADABLES

public static final Class<?>[] DEFAULT_UNREADABLES

These are classes that we never use for reading (never try to deserialize instances of these types).

DEFAULT_UNWRITABLES

Implementation will first check that expected media type is a JSON type (via call to hasMatchingMediaType(jakarta.ws.rs.core.MediaType)); then verify that type is not one of "untouchable" types (types we will never automatically handle), and finally that there is a deserializer for type (iff checkCanDeserialize(boolean) has been called with true argument -- otherwise assumption is there will be a handler)

locateMapper

public MAPPER locateMapper(Class<?> type,
                           MediaType mediaType)

Method called to locate ObjectMapper to use for serialization and deserialization. Exact logic depends on setting of JaxRSFeature.DYNAMIC_OBJECT_MAPPER_LOOKUP.

If JaxRSFeature.DYNAMIC_OBJECT_MAPPER_LOOKUP is disabled (default setting unless changed), behavior is as follows:

1. If an instance has been explicitly defined by setMapper(MAPPER) (or non-null instance passed in constructor), that will be used.
2. If not, will try to locate it using standard JAX-RS ContextResolver mechanism, if it has been properly configured to access it (by JAX-RS runtime).
3. Finally, if no mapper is found, will return a default unconfigured ObjectMapper instance (one constructed with default constructor and not modified in any way)

If JaxRSFeature.DYNAMIC_OBJECT_MAPPER_LOOKUP is enabled, steps 1 and 2 are reversed, such that JAX-RS ContextResolver is first used, and only if none is defined will configured mapper be used.

Parameters:

type - Class of object being serialized or deserialized; not checked at this point, since it is assumed that unprocessable classes have been already weeded out, but will be passed to ContextResolver as is.

mediaType - Declared media type for the instance to process: not used by this method, but will be passed to ContextResolver as is.
