Solving "JVM Terminated: How to Fix Exit Code=2"Error in Java Virtual Machine

The Java Virtual Machine (JVM) is a critical component of the Java platform, responsible for executing Java bytecode. Sometimes, JVM encounters errors that cause it to terminate abruptly. One such error is the "Exit Code=2" error. This guide will help you troubleshoot and fix the JVM terminated Exit Code=2 error in a step-by-step manner.

Understanding the Exit Code=2 Error

Exit Code=2 error occurs when the JVM terminates unexpectedly. This error is typically accompanied by a message, such as "JVM terminated. Exit code=2". The exit code is a numeric value that provides information about the reason for the termination. An exit code of 2 usually indicates that the JVM could not find the specified class or resource.

Common Causes of Exit Code=2 Error

There are several possible reasons for the Exit Code=2 error, some of which include:

  1. Incorrect classpath configuration
  2. Missing or corrupted Java libraries
  3. Incompatible Java version
  4. Insufficient memory allocation

Step-by-Step Guide to Fix Exit Code=2 Error

Step 1: Verify the Classpath Configuration

The classpath is a parameter that tells the JVM where to find the user-defined classes and libraries. An incorrect classpath configuration can result in the Exit Code=2 error. To fix this, you need to verify your classpath configuration.

  1. Open your Java project in an IDE or text editor.
  2. Check the classpath settings in your project's build configuration.
  3. Ensure that the classpath includes the required Java libraries and user-defined classes.
  4. Save the changes and restart the JVM.

Step 2: Check for Missing or Corrupted Java Libraries

Missing or corrupted Java libraries can also cause the Exit Code=2 error. To resolve this, you need to verify the integrity of the Java libraries in your project.

  1. Navigate to the folder containing the Java libraries.
  2. Verify that all required libraries are present and not corrupted.
  3. If you find any missing or corrupted libraries, download and replace them with the correct versions.
  4. Rebuild your project and restart the JVM.

Step 3: Verify the Java Version

Incompatible Java versions can lead to the Exit Code=2 error. To fix this, you need to ensure that your system is running the correct Java version.

  1. Open a command prompt or terminal window.
  2. Run the following command to check the installed Java version:
java -version
  1. Compare the installed Java version with the version required by your project.
  2. If the versions are incompatible, download and install the correct Java version.
  3. Restart the JVM and verify that the error is resolved.

Step 4: Increase Memory Allocation

Insufficient memory allocation can also cause the Exit Code=2 error. To fix this, you need to increase the memory allocated to the JVM.

  1. Open your project's build configuration or startup script.
  2. Locate the JVM arguments for memory allocation, typically represented as -Xmx and -Xms.
  3. Increase the values for these arguments to provide more memory to the JVM.
  4. Save the changes and restart the JVM.


1. Can I change the default exit code for JVM termination?

Yes, you can change the default exit code for JVM termination by invoking the System.exit() method with a custom exit code in your Java application.

2. How do I know if my Java libraries are corrupted?

Corrupted Java libraries may exhibit unexpected behavior, such as missing class files or incorrect file sizes. Downloading and replacing the libraries with the correct versions can resolve this issue.

3. How do I determine the required Java version for my project?

The required Java version for your project is typically specified in the project documentation or build configuration. Additionally, you can check the compatibility of your project's Java libraries with specific Java versions.

4. Can insufficient memory allocation cause other JVM errors?

Yes, insufficient memory allocation can cause other JVM errors, such as OutOfMemoryError or poor application performance. Increasing memory allocation can help resolve these issues.

5. How do I set JVM arguments in different Java IDEs?

Setting JVM arguments varies depending on the Java IDE you're using. Consult your IDE's documentation for instructions on setting JVM arguments.

Note: This guide provides general information on troubleshooting JVM terminated Exit Code=2 error. The specific steps and configurations may vary depending on your project, operating system, and Java version. Always consult your project's documentation and the official Java documentation for the most accurate information.
