Jackson 3.0.4: Global defaultAttributes Are Not Applied

[leonchen83]

I’m trying to use global attributes in Jackson 3 via JsonMapper.Builder.defaultAttributes(), but they don’t seem to take effect during deserialization.

Here is a minimal reproducible example:

static void main() {
    JsonMapper.Builder builder = JsonMapper.builder();
    builder.defaultAttributes()
           .withSharedAttribute("$test1", "A")
           .withPerCallAttribute("$test2", "B");

    SimpleModule module = new SimpleModule();
    module.addDeserializer(A.class, new ADeserializer());
    builder.addModule(module);

    JsonMapper m = builder.build();

    String json = m.writeValueAsString(new A());

    m.reader()
     .forType(A.class)
     .withAttribute("$test3", "C")
     .readValue(json);
}

static class ADeserializer extends ValueDeserializer<A> {

    @Override
    public A deserialize(JsonParser p, DeserializationContext ctx)
            throws JacksonException {
        while (p.currentToken() != JsonToken.END_OBJECT) {
            p.nextToken();
        }
        System.out.println(ctx.getAttribute("$test1"));
        System.out.println(ctx.getAttribute("$test2"));
        System.out.println(ctx.getAttribute("$test3"));
        return null;
    }
}

static class A {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Output:

null
null
C

This shows that only the per-call attribute ($test3) set via ObjectReader.withAttribute(...) is visible.

The global attributes configured through:

builder.defaultAttributes()
       .withSharedAttribute("$test1", "A")
       .withPerCallAttribute("$test2", "B");

are not available in DeserializationContext.

This suggests that defaultAttributes() on JsonMapper.Builder are not being applied (or propagated) during deserialization.
Am I missing something?
