The 'An Internal Error Occurred During Polling News Feeds' error is commonly caused by missing or incompatible javax/xml/bind/jaxbcontext dependencies. This issue usually arises when migrating from Java 8 to a later version, as the JAXB module has been removed from the default classpath in Java 9 and above.

Step-by-Step Solution

Step 1: Verify Java Version and JAXB Dependency

First, check your Java version by running the following command in your terminal or command prompt:

java -version

If you're using Java 9 or later, you'll need to ensure that your project has the necessary JAXB dependency. Verify if your project is using JAXB by looking for any imports related to javax.xml.bind in your code.

Step 2: Add JAXB Dependency to Your Project

If your project is missing the JAXB dependency, you'll need to add it. Here's how to add the JAXB dependency for Maven and Gradle projects:


Add the following dependency to your pom.xml:



Add the following dependency to your build.gradle:

implementation 'javax.xml.bind:jaxb-api:2.3.1'

Step 3: Update Your Code

After adding the JAXB dependency, you might still encounter issues with JAXB implementation. To resolve this, update your code to use the latest JAXB implementation. Here's an example:

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;

public class NewsFeedParser {
    public static NewsFeed parse(String xml) {
        try {
            JAXBContext jaxbContext = JAXBContext.newInstance(NewsFeed.class);
            Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
            return (NewsFeed) unmarshaller.unmarshal(new StringReader(xml));
        } catch (JAXBException e) {
            return null;

Step 4: Test Your Application

After updating your code, test your application to ensure that the 'An Internal Error Occurred During Polling News Feeds' error is resolved. If the issue persists, consider revisiting previous steps and verifying your project's dependencies and configuration.


1. What is JAXB?

JAXB (Java Architecture for XML Binding) is a Java-based technology that allows you to convert Java objects into XML and vice versa. It's commonly used for processing XML documents in Java applications.

2. Why was JAXB removed from Java 9?

JAXB was removed from Java 9 as part of the Java Platform Module System (JPMS) introduction. The goal was to create a more modular and lightweight Java runtime environment by removing less frequently used modules from the default classpath.

3. Can I use JAXB with Java 11?

Yes, you can use JAXB with Java 11. However, you'll need to manually add the JAXB dependency to your project, as it's no longer included in the default classpath.

4. Are there alternative libraries for XML processing in Java?

Yes, there are alternative libraries for XML processing in Java, such as XStream, DOM, and SAX.

5. Can I use JAXB in a modular Java application?

Yes, you can use JAXB in a modular Java application. However, you'll need to add the appropriate requires directive in your file, like this:

module your.module {
    requires java.xml.bind;
    // Other modules and dependencies...
