Upon Obtaining Custom Claim from a Signed and Encrypted JWT, Custom Claim, returned with no Data.

Using Maven Artifact: nimbus-jose-jwt with version 4.22,

A custom Claim added to a JWT which adds a named claim and that Object being a simple POJO that wraps the Map class. Debugging shows custom claim in the Token.

However, when i decrypt the payload, all other claims are correct, except the custom claim which should point to a valid Map, points to a property key, but it's claim value is of a zero length?

        // Retrieve the JWT claims...
        System.out.println("  Validating Claims...");
        if (!signedJWT.getJWTClaimsSet().getSubject().equalsIgnoreCase("[e-mail]")) {
            System.out.println("JWT Subject Claim did not Verify");
        }
        Map<String,Object> claims = signedJWT.getJWTClaimsSet().getClaims();
        System.out.println(signedJWT.getJWTClaimsSet().getClaim("sky"));
        // This claim will have no value?

Please advise if there is a work around.

User error. Pojo was defined without any setters, so the POJO in question would not be rendered.

Just double checked that we have a test for this in the suite - we do, so custom claim retrieval should work.

In a separate ticket there is a discussion about adding support for a @JWTClaim annotation, to enable objects with fields annotated with it to be converted automatically to a JWT claims set. Is such an annotation going to be of use in your project? I'm trying to get developer feedback on this.

Thanks,

Yes I would be very interested in the @JWTClaim Annotation. Many Thanks, Jeff
