jackson: v3 generating wrong jackson annotation import statements

[ophalsp]

When running the openapi-processor-spring with mapping jackson: v3,

openapi-processor-spring: v1
options:
  spring:
    annotations: exchange
  package-name: some.packagename
  jackson: v3
  javadoc: true

Creating an enum like this

    DummyEnum:
      type: string
      enum:
        - A
        - B
        - C

results in generated codes that looks like this:

package some.packagename.model;

import some.packagename.support.Generated;
import tools.jackson.annotation.JsonCreator;
import tools.jackson.annotation.JsonValue;

@Generated(
    value = "openapi-processor-spring",
    version = "2026.3",
    date = "2026-07-09T09:58:18.081946317Z")
public enum DummyEnum {
  A("A"),
  B("B"),
  C("C");

  private final String value;

  DummyEnum(String value) {
    this.value = value;
  }

  @JsonValue
  public String getValue() {
    return this.value;
  }

  @JsonCreator
  public static DummyEnum fromValue(String value) {
    for (DummyEnum val : DummyEnum.values()) {
      if (val.value.equals(value)) {
        return val;
      }
    }
    throw new IllegalArgumentException(value);
  }

}

You will notice the tools.jackson.annotation.JsonCreator import statement which is incorrect, it should be com.fasterxml.jackson.annotation.JsonCreator.
To my knowledge the Jackson annotations, and only the annotations, have kept the old package name structure in the Jackson v3 version.
See the jackson release notes, under the Major changes section

just remove the jackson option.

I was not aware of the unchanged package names when I added that.. 😬 The idea then was to keep it hidden.

Since it is in the documentation (ups..) that didn't work to well 😀
