You may have read about OpenJDK Platform Binary if you often use Java-based applications. However, many Java users still need to learn what it is and how it works. As a result, Open JDK, as well as its binaries, are frequently disregarded.
Therefore, here is the spot to understand much about Java’s OpenJDK and its Platform Binary. So keep reading this post until the end to learn how to solve its infamous high CPU usage issue.
What Is OpenJDK Platform Binary?
Sun Microsystems’ Java SE Platform Edition is available as part of the OpenJDK Platform Binary project, which is free and open source. Oracle Corporation first created it in 2006 as a component of its efforts on Java Community Process (JCOP).
The initial iteration of OpenJDK was made available by Oracle in 2008 under the terms of GNU GPL (General Public License), which permitted free distribution and code modification.
Since then, several more businesses—including IBM, Azul Systems, Red Hat, SUSE Linux, SAP, and others – have joined the initiative. OpenJDK’s most recent release is v8u151.
Since 2007, there have been many OpenJDK Platform Binary projects. Nevertheless, they didn’t begin distributing the Platform Binary until 2013. The OJRE, or OpenJDK Runtime Environment, is another name for this binary.
Since it has all the classes required to run your applications, it is known as a “runtime” environment. So, the JVM is what we refer to when we discuss the runtime environment.
The JVM, known as HotSpot, also receives updates and fixes bugs from the OpenJDK Project. The OpenJDK Development Kit provides these changes (ODK).
In addition, ODK is a collection of tools that aid in developing and testing new JVM features and improvements.
How Does It Work?
The OpenJDK performs similarly to other JVMs. You start by using Java to compile a class file (.class). The .class files are then connected using it. The resulting executable is then launched.
The lack of a standard library out of the box is the main contrast between OpenJDK and other JVMs.
Instead, it uses a variety of other libraries, including Apache Harmony and Bouncy Castle. Any and all such libraries are available in the ODK.
Why Should You Use OpenJDK Platform Binary?
Performance, security, and licensing are the key factors influencing people’s decisions to utilize OpenJDK Platform Binary rather than the proprietary JVMs provided by Oracle and other companies.
1. Enhancing Performance
If security concerns you, you should be aware that OpenJDK was developed utilizing the same technologies as Oracle’s private JVM. Consequently, you shouldn’t worry about adding more software to your computer to protect it.
2. Strengthening Security
OpenJDK mostly depends on other libraries, as was already said. Some of them even come with GPL licenses. This suggests that there are no royalties due while utilizing them.
Moreover, several languages, like C++, C, and others, are developed in their native languages. As a result, they outperform Java-based solutions by a wide margin.
3. Easier Licensing
If you follow the guidelines of the GPL, you are not needed to pay anything to utilize OpenJDK. If you decide to purchase a commercial license, you can combine the ODK, JDK, and JRE.
How To Fix OpenJDK Platform Binary High CPU Usage?
Many users have reported that using OpenJDK Platform Binary causes various other applications to slow down. Most users have reported this while playing video games like Minecraft and Grand Theft Auto V.
Here, they noticed that OpenJDK Platform Binary utilizes 100% of the CPU, making other applications run slower. Therefore, if you are facing this same situation, follow these steps below to fix it:
1. Update Your Graphics card Driver
A slow graphic drive can increase the CPU use of the OpenJDK platform binary. As a result, you can fix the problem by updating your graphics driver.
- First, access Device Management by right-clicking the Start menu and selecting it.
- Next, upgrade the graphics driver by using the right-click menu.
- Now, you may select either Browse my computer for drivers or Search automatically for drivers.
2. Disable Integrated Graphics Card From BIOS Settings
By turning off Integrated Graphics in the BIOS, you may also try to resolve the high CPU issue with the OpenJDK platform binary.
- Hit Win + I at the same time to launch Settings.
- Click on Updates & Security by scrolling down.
- Click on the Restart Now option under Advanced Settings in the Recovery tab to bring up the Windows recovery settings on your machine.
- To boot your computer into UEFI BIOS, select UEFI Firmware Settings.
- Within Onboard Devices, Integrated Peripherals, or Built-in Devices, look for a setting with onboard, integrated video, or VGA.
- Press Enter to switch integrated graphics off or deactivate.
- Press the matching F-key to save all your changes so far, followed by clicking on Y to confirm your choice, as directed by the on-screen instructions.
3. Do A Full System Restore
You can try restoring the system to resolve the “OpenJDK platform binary high CPU” problem if the fixes above don’t work. You should know that you can only use this approach if you have already made a system restore point. To achieve it, adhere to the advice below:
- Fist, build a recovery drive in the start menu and click on it. This will take you to a system properties’ system protection tab.
- Then, select System Restore.
- Now, choose the system restore point you wish to go to. Next, complete the work by adhering to the on-screen directions.
Final Thoughts
In conclusion, the OpenJDK platform binary is a variety of things. It primarily provides customers with the source code needed to give them a large selection of distributions to choose from to execute their apps. Moreover, it offers a transparent and inclusive framework for defining the Java platform’s future.
After reading this post, you may learn how to solve its high CPU usage issue. You can attempt each of the fixes above separately if you wish to resolve the problem but need help with how to do so.
