java.lang.NoSuchMethodError: java.time.Instant.<init>()

Question

I get the error java.lang.NoSuchMethodError: java.time.Instant.<init>() when in a rest-API documentation (swagger) I try to do a post request with as body the following json:

{
  "accountId": "string",
  "name": "string",
  "value": "string",
  "expires": 0
}

this maps to the model:

AccountClientIdentifierEntity{
accountId   string
name    string
value   string
expires integer($int64)
}

Now in my Java code this expires attribute is actually an Instant, but it somehow gets parsed as an Integer here, so I guess my problem lies here, when I post with the "0" instead of an Instant. Can someone help me to fix this, or at least catch the error correctly?

Full code: Entity:

/**
 * The Class UserEntity.
 */
@XmlRootElement(name = "accountClientIdentifier")
@XmlType(propOrder = { "accountId", "name", "value", "expires"})
@JsonInclude(JsonInclude.Include.NON_NULL)
public class AccountClientIdentifierEntity {

    public static void registerToContextProvider(){
        try {
            CustomContextProvider.registerClass(com.inteno.iopsys.plugin.restapi.entity.AccountClientIdentifierEntity.class);
        } catch (Exception e){
            Log.error("Could not register AccountClientIdentifierEntity: "+e.getMessage());
        }
    }

    /** The username. */
    private String accountId;

    /** The name. */
    private String name;

    /** The value. */
    private String value;

    /** expires. */
    private Instant expires;


    /**
     * Instantiates a new user entity.
     */
    public AccountClientIdentifierEntity() {

    }

    /**
     * Instantiates a new user entity.
     *
     * @param accountId
     *            the account ID
     * @param name
     *            the name
     * @param value
     *            the value
     */
    public AccountClientIdentifierEntity(String accountId, String name, String value) {
        this.accountId = accountId;
        this.name = name;
        this.value = value;
    }

getters & setters

service path:

@POST
    @Path("/identifiers")
    @ApiOperation(value = "Add a new account client identifier")
    @ApiResponses(value = {@ApiResponse(code = 201, message = "Created")})
    public Response createAccountClientId(
            @ApiParam(value = "The new identifier to create", required = true) AccountClientIdentifierEntity accountClientIdentifierEntity
    ) throws ServiceException {
        controller.createOrUpdateAccountClientIdentifier(accountClientIdentifierEntity);
        return Response.status(Response.Status.CREATED).build();
    }

You're asking JAXB to put the peg (a number value received from the JSON and identifier by swagger as $int64) in the hole (the Instant expires; field in your AccountClientIdentifierEntity class).

Turns out, that's a square peg and a round hole. JAXB tries its best, and given that it has no idea what an Instant might be, is planning to construct one and perhaps find a set method maybe. That's not how Instant works, however; you're looking specifically for Instant.ofEpochSecond or ofEpochMilli, and we are now truly getting into the root issue here: What does that $int64 even mean? Is it seconds since 1970? milliseconds? Nanofurlongs? Perhaps it's days since 1902, using the decimal fraction for hours and seconds?

Asking JAXB to just take a flying wild stab at it seems unreasonable, and indeed, isn't a thing JAXB can do, nor will it ever. You must tell it what to do.

To do this, you tell JAXB that there is a specific unmarshaller available for that field.

An @XmlJavaTypeAdapter annotation should be able to do the job; you can annotate the expires field with it, passing a class reference to a class that implements XmlAdapter.

The jaxb-java-time-adapters project could be useful here; possibly only to look at the source to know what to do.
