Not all Java virtual machine errors are the same. They can occur for many different reasons. In this article, we will explain the most common causes of Java virtual machine launcher error – Could not create the Java Virtual Machine and how to fix it.

What is Java in simple words?

Java is a popular programming language that can run on a variety of different operating systems and devices. It has many different uses, including in web development, mobile applications, desktop applications, and server-side programming. Java generates a virtual machine (VM) that executes the code written in Java. A Java virtual machine launcher error can occur if something goes wrong with the data or code that’s being processed by the Java virtual machine.

What is a Java virtual machine error?

A Java virtual machine error, also known as a JVM error, is classified as an error generated by the Java Virtual Machine. When this type of error occurs, it usually means that the computer cannot read or understand the code. This can happen for a number of reasons, such as when the computer isn’t updated with required patches or if it’s not compatible with Java. If you come across a JVM error while using your computer, it’s important to know how to recover from this problem. Here are some steps to take in order to fix this issue and continue using your computer.

Если ваша система частенько выдает сообщения об ошибках запуска Java Virtual Machine «виртуальной машины Java», вам не нужно беспокоиться, эти ошибки очень легко устранить.

Функции JVM (Java Virtual Machine)

Виртуальная машина java отвечает за выделение памяти и сбор мусора, наряду с интерпретацией байт-кода в машинный код.

Среда выполнения Java (JRE) является обязательным для установки на вашем компьютере для некоторых приложений, чтобы работать должным образом. Основным компонентом JRE является виртуальная машина Java (JVM), которая помогает запускать Java-приложения. Java-файл, при компиляции, производит ‘.класс’ файл, а не исполняемый файл. Этот класс файл содержит байт-код java, который в jvm интерпретируется в машиночитаемые инструкции. Jvm — независит от платформы, поскольку он обеспечивает машинный интерфейс, который не зависит от базовой операционной системы и аппаратной архитектуры.

Могут быть случаи, когда вы можете получить сообщения об ошибках при запуске jvm, в таких ситуациях, как загрузка в компьютер, игра в игры, такие как minecraft, или открытие определенных Java-приложений.

Java is a versatile, machine-independent programming language that is used to write a variety of different applications. Unlike most other applications, you can run java applications equally well in Windows, Mac, or Linux, provided you have installed Java Virtual Machine (JVM) in your system. However, if JVM breaks, then none of your java applications run.

One recent impact having a broken JVM launcher was felt by users of Minecraft. A recent update brought new features, but also required Java 16 to set up a server. Those with older version of JVM were greeted with a Java Native Interface (JNI) error.

There are other examples where a malfunctioning JVM launcher caused an application to not work, and it could probably happen again in the future. We have this article prepared, so that you can be prepared when your JVM launcher has an error.

What Causes Java Virtual Machine Launcher Errors

You can somewhat diagnose what is wrong with your JVM and attempt a corresponding fix based upon the type of error message that you see when you JVM does not work.

Reinstall/Update Java

If the error message you see is “Java Virtual Machine Launcher Could Not Find The Main Class,” then Java has been incorrectly installed or Java installation has been corrupted in your machine.

JNI errors can be caused by outdated version of Java.

To fix this, you need to reinstall Java Runtime Environment.

Windows 10

1. Launch Settings (Press Win + I), then navigate to Apps.
2. Scroll to find Java and select Uninstall.
3. Download and install the latest version of Java.
4. Restart your computer.

Windows 11

1. Launch Settings, navigate to Apps > Apps & features.
2. Scroll to find Java.
3. Click on the kebab button to its right, then select Uninstall.
4. Download and install the latest version of Java.
5. Restart the computer.

Increase System Memory for Java

You will get a “Could not create the Java virtual machine” error if Java is trying to use more memory than has been assigned to it.

You can fix this by increasing the amount of memory allotted to Java.

Note: The variable value -Xmx512M sets memory available to Java to 512 MB. You can change this value depending upon how much memory your Java was utilizing before. For instance, setting this to -Xmx1024M assigns 1024 MB system memory to Java.

Run as Administrator

Sometimes JVM errors can occur because you do not have sufficient user privilege to run the application.

You can fix this by configuring Java to run as administrator.

1. Press Win + E to launch Windows Explorer, then navigate to Java installation folder. (Usually located at “…/Program Files(x86)/Common Files/Oracle/Java/javapath”)
2. Find java.exe and right-click on it.
3. Select Properties.
4. Switch to Compatibility tab and put a tick mark on Run this program as an administrator.
   
5. Click Apply, then click OK.

Set File Type Association to Java

If your error message is “Unable to access Jar file,” then one of the reasons for this issue is that your jar file association is not set to Java.

Windows 10

1. Launch Settings (Press Win + I)
2. Navigate to Apps > Default apps.
3. Click on Default apps by file type.
4. Scroll to find .jar from the list of file types.
5. Click on the currently set default application next to it.
6. Click on Java(TM) Platform SE binary.
   
7. Close Default apps setting.

Windows 11

1. Press Win + I to launch Settings.
2. Navigate to Apps > Default apps.
3. Enter .jar file type in the box under Set a default for a file type of link type.
4. Click on the application that is currently selected to open .jar files, then click on Java under Other options.
5. Close settings.

Frequently Asked Questions

What is Java Exception Error?

And exception is an unexpected event which occurs during program execution. Java has methods to catch and handle exceptions.

An application that has implemented exception handling methods will create an exception object when it runs into an exception during execution.

The object contains information such as name and description of the exception, as well as the state of the application when the exception was caught.

What is the Maximum Java Heap Size for Windows?

The maximum allowable heap size for Java in Windows is 16 EB (exabyte). For 32 bit of Windows, maximum heap size is 4 GB.

How Do I Install Java on Mac?

Please follow the steps below if you want to install Java on your MacOS:

1. Download jre-8u65-macosx-x64.pkg from the official site.
2. Launch the file by double clicking on it.
3. Double click the package icon to launch Install Wizard.

Over the years, computers have gotten relatively better at providing useful error messages. However, due to the complexity of modern software, sometimes you need a degree to even understand what you’re being told.

In this article, we’ll explain what the most common Java Virtual Machine errors mean and how you can resolve the underlying issues. Before we get to that, though, we first have to understand what a virtual machine is. Shall we begin?

What Is A Virtual Machine?

In layman’s term, a virtual machine allows your computer to simulate an entirely separate system. This makes it possible to run programs that otherwise wouldn’t be compatible with your system architecture – for instance, Android apps on a Windows PC. So what does this have to do with Java?

When a Java file is executed, it’s run through a version of the Java Virtual Machine before the code is interpreted. This means that if there’s a problem with the virtual machine, you won’t even be able to run Java programs until it’s been resolved.

“Java Virtual Machine Launcher Could Not Find The Main Class”

This sounds like a pretty serious error but in actuality, it’s one of the easiest to fix. Generally, if you’re seeing this, something has gone wrong with your Java installation. All you have to do is reinstall it. To do this:

• Uninstall your previous Java installation. For Windows users, this is done in the Control Panel’s Programs and Features submenu.

• Next, go to Java’s site and select the correct version for your operating system.
• Restart your computer and try running the Java file again.

“Could Not Create The Java Virtual Machine”

Here’s another example of a vague error message that doesn’t actually help you in any way. The good news is that this error usually has one specific cause: Java is trying to use more memory than your system actually has. So how do you fix this?

• Begin by opening the Control Panel.
• Click System, then Advanced Systems Properties, then Environment Variables

• Click the Add button
• Set the New Variable Name to “_JAVA_OPTIONS” without the quotation marks.
• Set the value to “-Xmx512M” without the quotation marks. The digits before the M refer to the maximum amount of RAM allocated to Java. For instance, you could also use “-Xmx1024M” or “-Xmx256M”, if you had more or less memory to spare.

Fixes To Avoid

There are a few solutions that users on internet forums LOVE to suggest, but while they mean well, you are highly unlikely to see your problem resolved by:

• Running an anti-malware scan (a virus that only messes with your Java Runtime Environment? For what purpose?).
• Clearing your cache. This has nothing to do with Java, whatsoever.

• Changing registry values. While this has the potential to resolve very specific problems, it can have catastrophic effects on your operating system and you’re more likely to break something than fix it.
• Reinstalling your operating system. This is like amputating an arm because of a broken fingernail! Problems with a single software package can be easily resolved and won’t lead to you losing all your files, as with a fresh installation.
