Step 1: Verify Your JDK Version

Ensure you’re using a compatible JDK version. Java 8 and later versions are recommended for most applications. If you’re using an earlier version, consider upgrading to a supported version.

java -version

Check the output to verify your JDK version.

Step 2: Check for Conflicting Dependencies

Review your project’s dependencies and libraries. If you’re using a build tool like Maven or Gradle, examine the pom.xml or build.gradle file for any conflicts.

<dependency>
    <groupId>javax.management</groupId>
    <artifactId>jmx</artifactId>
    <version>1.2.1</version>
</dependency>

Make sure you’re not including duplicate or conflicting JMX-related dependencies.

Step 3: Inspect Classpath and Jar Files

Verify that the java.lang.management.ManagementFactory class is available in your classpath. Check your project’s classpath settings and ensure that the necessary jar files are included.

Jar File	Contents
java.management.jar	Including java.lang.management.ManagementFactory
jmx.jar	Including javax.management.* classes

Double-check that you haven’t accidentally excluded or misplaced these jar files.

Step 4: Reinstall Java or Update Java Installation

If you’ve ruled out the above steps, it’s possible that there’s an issue with your Java installation. Try reinstalling Java or updating your installation to the latest version.

sudo apt-get update
sudo apt-get install openjdk-8-jdk

For Windows users, download and install the latest JDK from the official Oracle website.

Step 5: Clean and Rebuild Your Project

Lastly, try cleaning and rebuilding your project to ensure that all dependencies are correctly resolved.

mvn clean package

For Gradle users:

gradle clean build
