What is Openjdk Platform Binary?

Programming languages are crucial bridges between the developer and the system. Languages like Python, Java, JavaScript, etc are popular in the programming industry. Each programming language has a different working environment, including several tools and features. One such environment of the Java language is the OpenJDK platform binary.

OpenJDK is a part of the Java Standard Edition (JSE) platform. An open-source environment, it is popularly used to develop and run several games. For the majority of the time, users are unaware of the “OpenJDK” term. Being a critical part of the Java code execution, it becomes crucial to know OpenJDK. With this article, we will try to learn about OpenJDK, the OpenJDK platform binary, its effects on the system’s CPU, and related solutions.

OpenJDK is one of the open-source and free implementations of Java Standard Edition. Released in 2006 as a part of the Java Community Process, the OpenJDK project was introduced with several versions till 2013. In 2013, a separate platform binary for OpenJDK was released, which worked as a runtime environment.

The OpenJDK platform binary contained all the necessary classes to run a program. Being a part of Java Virtual Machine, it also provides important bug fixes and updates. The updates are then implemented via ODK (OpenJDK Development Kit). OpenJDK becomes an important link for the security and performance of the program classes.

Working of OpenJDK

The working of OpenJDK is no different than most JVMs. It starts by adding a class file (.class) which is later compiled by using the Javac command. The next stage involves linking the class file with the help of Id. This step is important for the execution of the file since any diversion would show an error in the execution process. Upon successful execution, the program runs without any errors.

Compared to any JVM, the OpenJDK platform binary has a unique distinction: the absence of a standard library. OpenJDK uses third-party libraries from organizations like Apache, BouncyCastle, to compensate for the standard library. While working, the OpenJDK platform binary tends to use 100% of the CPU, which causes several issues to the system. Being a major problem, we will try to understand the reasons behind this issue.

High CPU Usage In OpenJDK Platform Binary

The CPU consumption varies depending on the intensity of the running program. OpenJDK has to execute a Java code that includes several steps mentioned in the working OpenJDK section. Due to the allotment of a high number of resources to the OpenJDK platform binary, the load on the CPU spikes. Sometimes, even with a high-end CPU, the high usage problem exists for different reasons.

Several bugs plague an outdated version of the OpenJDK platform binary. Similarly, incompatible resources cause frequent errors, increasing the CPU load. Other factors like malware, file corruption, or memory leaks also cause a high load on the CPU. We have compiled some solutions to prevent the CPU from reaching high usage conditions in the next section.

Fixing High CPU Usage Caused By OpenJDK Platform Binary

To prevent or fix high usage problems with CPUs, users must first identify the problem’s source. For the majority of the time, users can take some preventive measures. If the problem exists even after taking these measures, users can follow certain solutions mentioned below.

1. Updating Graphics Driver

When the graphics drivers are outdated, data bottlenecking happens at the graphics cards. Due to the inefficiency caused by the outdated drivers, the GPU load increases, eventually affecting the CPU. To solve this problem, users must check for driver updates. With the help of device management of the system, the driver can be updated to reduce CPU usage.

2. Disabling Integrated Graphics

Integrated graphics shared memory with the system’s CPU. When the data flow is high, it sometimes causes high-usage problems. To prevent this, users can reduce the load on the shared memory. With the help of BIOS, the integrated graphics can be disabled for the time being. Users can also opt for a detected graphics unit which ultimately lowers the tasks on the CPU.

3. System Restore

Sometimes, performing a system restore fixes most problems,, including OpenJDK and CPU-related issues. However, this option works effectively when it is done from a saved restore point. With the help of a recovery drive and system protection options, users can easily follow the system restore process.

4. Changing the In-App Settings

Most of the time, the high-CPU usage problem arises when the system cannot handle processes from OpenJDK. When the system specifications are lower than the specified limit, it fails to deliver the required power for the OpenJDK platform binary. To resolve this issue, users can change the settings of the root application. Changing the settings limits CPU usage, which prevents the system from freezing.

5. Updating Java Version

Apart from the driers, it is equally important to keep Java updated. Some underlying bugs affect the working of OpenJDK, which cause the spike-usage of the CPU. Updating Java to the latest version means all the bugs are fixed and no longer cause any trouble.

6. Reinstallation of the Application

Users can also check the application for issues that cause load on the CPU. Problems in the application can be fixed by updating its program. Users can then reinstall the application to remove any remaining bugs from the software.

7. Reducing the Rendering Distance

When OpenJDK is used for games like Minecraft, users can change the game settings to reduce the load on the CPU. The “rendering distance” option controls the rendering of graphics against a certain distance. When this option is set to a higher value, more resources are used to render a larger area. By lowering the value for the “rendering distance” option, CPU usage decreases due to a lower number of resources in use.

OpenJDK Platform Binary – FAQs

1. Why does OpenJDK use so much CPU?

Ans: Several factors like outdated graphic drivers, etc cause higher usage of CPU outdated graphic drives poorly handle tasks leasing out a bottleneck process. Similarly, dedicated graphics use a shred of memory, with the CPU increasing its usage. Other factors like outdated Java, incompatible system specs, etc, also spikes the CPU usage.

2. Is OpenJDK and Java different?

Ans: Both OpenJDK and Java are interrelated, with some major differences. OpenJDK is a part of the Java programming environment. On the other hand, Java is a programming language used to write codes for several types of applications. OpenJDK has several tools that help in executing the Java program.

3. Why is OpenJDK used for Java applications?

Ans: OpenJDK plays a crucial role in several Java applications. It helps in executing the class file of the source code. With the help of libraries, it can add important classes to Java applications. Besides this, OpenJDK also plays an important role in debugging Java applications.

4. Does the OpenJDK platform binary have any security considerations?

Ans: OpenJDK does not need external security software to secure the system against threats. However, maintaining OpenJDK is crucial to keep it away from any threats. Updated versions are more secure than the outdated version. Checking the platform binary for vulnerabilities helps secure them against possible injecting attacks.


Understanding the OpenJDK platform binary gives us a basic idea of its importance for Java applications. OpenJDK becomes crucial for developing Java applications by providing a suitable runtime environment. It plays a major role in controlling the execution of program files, adding security patches, debugging applications, and other processes. We have also gone through the major problem experienced by users via the OpenJDK platform binary: high CPU usage. With this article, the user becomes aware of the causes and solutions for higher CPU usage.
