Actual implementation of JSR-353 (JSON)?

Question

For handling JSON in Java, the following specifications have been published by the JCP:

• JSR 374: Java™ API for JSON Processing 1.1
• JSR 353: Java™ API for JSON Processing (1.0 – predecessor to JSR 374)

Built on top of those is the specification for JSON-to-Java data-binding:

• JSR 367: Java™ API for JSON Binding (JSON-B)

Are there any implementations of these APIs?

Answer 1

Reference implementation

JSON-P is the reference implementation for JSR 374 (& 353). May or may not be a competitive one, in terms of feature and performance. This code is included as a part of Glassfish, the reference implementation of Java EE.

For the binding spec, JSR 367, the reference implementation is Eclipse Yasson.

Answer 2

Genson

Besides the reference implementation shown in correct Answer by Yu, another implementation of JSR 353 is Genson. See the project page and the GitHub page.

While I have not used it, the documentation claims to be a complete implementation of JSR 353. I do not know if it has been updated to the follow-up spec, JSR 374.
