### Question:
ServerSentEventAuthorizationResponseCore { public String getOrgUserHash() { return orgUserHash; } @JsonCreator  ServerSentEventAuthorizationResponseCore(
            @JsonProperty(value = "auth", required = true) String auth,
            @JsonProperty(value = "auth_jwe", required = false) String authJwe,
            @JsonProperty(value = "user_push_id", required = true) String userPushId,
            @JsonProperty(value = "service_user_hash", required = true) String serviceUserHash,
            @JsonProperty(value = "public_key_id", required = true) String publicKeyId,
            @JsonProperty(value = "org_user_hash") String orgUserHash
    ); String getAuth(); String getAuthJwe(); String getUserPushId(); String getServiceUserHash(); String getOrgUserHash(); String getPublicKeyId(); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testOrgUserHash() { assertEquals("OUH", new ServerSentEventAuthorizationResponseCore(null, null, null, null, null, "OUH").getOrgUserHash()); }
@Test public void testParseWithoutOrgUserHashIsNull() throws IOException { String json = "{\"auth\":\"Auth\", \"user_push_id\":\"UPID\",\"service_user_hash\":\"SUH\"," + "\"public_key_id\":\"PKID\"}"; assertNull(new ObjectMapper().readValue(json, ServerSentEventAuthorizationResponseCore.class).getOrgUserHash()); }
