Resolving ‘unsupported Major.minor Version 52.0’ In Java

Resolving ‘unsupported Major.minor Version 52.0’ In Java


When working with Java applications, you may encounter an error message indicating “unsupported major.minor version 52.0.” This error typically occurs when attempting to use Java Development Kit (JDK) 11 or later with Java Runtime Environment (JRE) 8 or earlier.


To resolve this issue, ensure that the JDK version used for compilation and execution matches the JRE version installed on the system. Here are the steps to follow:


1. Check Installed JDK Version:

Open a terminal or command prompt and run the following command to check the installed JDK version:

java -version

Look for the line that starts with “java version,” which will indicate the installed JDK version.

2. Check JRE Version:

Run the following command to check the installed JRE version:

javac -version

Again, look for the line that starts with “java version,” which will show the JRE version used by javac, the Java compiler.

3. Resolve Version Mismatch:

If the JDK and JRE versions do not match, you need to either install the appropriate JRE or use the correct JDK for compilation.

  • Install Matching JRE: Download and install the JRE that corresponds to the installed JDK version.
  • Use Correct JDK: If you prefer to use a different JDK version than the JRE installed, set the JAVA_HOME environment variable to point to the desired JDK directory:
export JAVA_HOME=/path/to/desired/jdk

4. Restart Services:

After making changes to the JDK or JRE, restart any running services that rely on Java, such as web servers or application servers.

5. Check Result:

Recompile and run your Java application to verify if the issue is resolved. If you still encounter the error, double-check the installed JDK and JRE versions and ensure the JAVA_HOME variable is set correctly.

Remember, always check for the latest versions of JDK and JRE to stay up-to-date with security patches and improvements.

  1. I’m having the same issue. How do I resolve this error? I’ve tried updating my Java version, but it didn’t work.

  2. This error occurs when you’re using an unsupported version of Java. Make sure you’re using the latest version of Java 8 or later.

  3. This is ridiculous! I can’t believe Oracle is still making us update our Java versions. This is a major inconvenience.

  4. I don’t think it’s fair to blame Oracle. They’re just trying to keep up with the latest security updates. We should be grateful that they’re still supporting Java.

  5. Oh, the irony! Oracle, the company that’s always complaining about piracy, is now forcing us to update our software. How hypocritical!

  6. Wow, thanks Oracle. I guess I’ll just stop using Java altogether. It’s not like I need it for anything important, right?

  7. I’m starting to think that Oracle is run by a bunch of monkeys. They can’t seem to get anything right!

  8. I’m still getting the error even after updating to the latest version of Java. What am I doing wrong?

  9. Make sure you’re using the correct version of Java for your operating system. Also, check your environment variables to make sure they’re set up correctly.

  10. This is the worst error message ever! It doesn’t tell me what’s wrong or how to fix it. Oracle needs to do a better job of writing error messages.
