JWT Authentication in JAVA throwing error as decryptPrivateKeyInfo(Unknown Source)

I am trying to upload the files to BOX using a service account, with JWT authentication.
I have set up a custom APP in Box, and is authorized by Admin. The Appication access is set to "Application", and application scope includes "Read/write all files/fodlers in Box" and "Mange Users". The Advanced Features is to "Generate User Access Token"

I am able to access the files using a Box developer token from this Box App.

But while using JWT authentication I am getting the error as at line
BoxDeveloperEditionAPIConnection client = BoxDeveloperEditionAPIConnection.getAppEnterpriseConnection(boxConfig, accessTokenCache);

Exception in thread "main" java.lang.NoSuchFieldError: id_hmacWithSHA3_224

I am following below Box article, and have installed JCE as instructed(We are located in US). We have JRE 1.8 installed and am using JAVA for development
https://github.com/box/box-java-sdk

Below is the code I am following:

// Read config file into Box Config object
Reader reader = new FileReader("F:\\BOX_CONNECTOR\\config\\48245_f10g2l6t_config.json");
BoxConfig boxConfig = BoxConfig.readFrom(reader);

// Set cache info
int MAX_CACHE_ENTRIES = 100;
IAccessTokenCache accessTokenCache = new InMemoryLRUAccessTokenCache(MAX_CACHE_ENTRIES);

BoxDeveloperEditionAPIConnection client =
BoxDeveloperEditionAPIConnection.getAppEnterpriseConnection(boxConfig, accessTokenCache);

// PERFORM ACTIONS WITH CLIENT

String filePath = "E:\\emltopdf-app-strap03.txt";
String fileName = "TESTJWT";
String folderId = "***number removed for privacy***99";

// Select Box folder
BoxFolder folder = new BoxFolder(client, folderId);

// Upload file
FileInputStream stream = new FileInputStream(filePath);
BoxFile.Info newFileInfo = folder.uploadFile(stream, fileName);
stream.close();
