Peripheral causes of high Java CPU usage
poorly configured Java GC; issues more correctly attributable to the software stack; thread synchronization, contention and deadlock issues; and. underlying file and database I/O problems.
If you run many programs at once, or if some programs are doing a lot of work, a higher percentage of both of these things will be used. If the CPU usage is around 100%, this means that your computer is trying to do more work than it has the capacity for.
Recommendations to lower Memory and CPU usage
Increase JVM memory limits to better handle spike load. Change default timeout settings to avoid piling up of requests. Perform an audit on default settings of the application server.
CPUs are designed to run safely at 100% CPU utilization. However, these situations can also impact the performance of high-intensity games and applications. Learning how to fix high CPU usage can resolve some of the most common problems.
Keeping old versions of Java on your system presents a serious security risk. Uninstalling older versions of Java from your system ensures that Java applications will run with the latest security and performance improvements on your system.
GPU for Minecraft. Unlike most games, Minecraft is more dependent on your CPU than your GPU. That means that the power of your CPU has a greatest impact on your computer's performance, and your CPU will often be the component limiting your FPS.
Experiencing 100% CPU usage while gaming may not necessarily be harmful, but it can lead to performance issues and affect the overall gaming experience.

While a Java application is running, the Java virtual machine (JVM) process may consume a large amount of CPU. In this case, the performance of the Java application deteriorates.

Overclocking temperatures could in theory go as high as 90°C while still being 'safe', and the max temperature for many CPUs is listed in the 105-110°C range. But for long-term use, you're much better off keeping things below 80°C in general and only pushing up to 85°C at the most.
Is 80c CPU usage bad Generally, it is recommended to keep your computer components between 60°C and 85°C under heavy load. 80°C is high, but it's well within the safe temperature range. It's only when it reaches 100°C that it gets dangerous.
You can uninstall older versions of Java manually in the same way as you would uninstall any other software from your Windows computer. Older versions of Java may appear in the program list as J2SE, Java 2, Java SE or Java Runtime Environment.
Removing all versions of Java might cause some applications to stop working. We would recommend installing an up-to-date JRE to run Java applications and contacting the application vendor if some application will not run with the most current version.
If your computer can use higher FPS, it means that your screen will show more images per second. This lets you see smoother animations. Lower frame rates make your Minecraft gameplay look laggy or stuttering. And because stuttered gameplay is not enjoyable, a 60 FPS is already a good standard.
Is high CPU usage bad Every PC will go through cycles of high CPU usage — there is nothing wrong with that. However, If your CPU usage is constantly high or even at 100%, there is definitely a reason for concern. Your CPU heats up when under heavy loads.
You don't want to push a CPU past its limits. Most seasoned gamers and computer techs recommend a threshold of 80 percent CPU usage for a reason. That extra 20 percent provides enough wiggle room for any background processes and the occasional CPU spike.
Definitely. Simply said, if the graphics card you are using isn't fast enough to produce as many frames as your CPU, then upgrading your CPU will not make a positive change to your FPS.
If your computer is low on memory it may use the CPU to compensate for the lack of memory, adding more RAM can help lower the CPU usage. It's important to have enough RAM for the tasks you are performing to reduce CPU usage.
Java technology is used by more than 6 million developers and runs on more than 5.5 billion devices.
Is it dangerous Generally, it is recommended to keep your computer components between 60°C and 85°C under heavy load. 80°C is high, but it's well within the safe temperature range. It's only when it reaches 100°C that it gets dangerous.
Anything under 60 degrees Celsius, or 140 degrees Fahrenheit, is expected. However, issues can creep up as things get hotter. Between 70 and 80 degrees Celsius (158 to 175 degrees Fahrenheit) is a safe range for gaming. It indicates that the CPU is working hard, but there's not much worry about lasting issues.
At the highest loads, your average CPU temps can go up to 80–85°C, but consider this the absolute limit. Sustained CPU temps above 80°C can do long-term damage to the CPU and its silicon. If your CPU goes higher than 90°C for several hours, it will likely reduce the lifespan of your processor.
Is 85-90 degrees too hot for a CPU/GPU Yes, 85-90 degrees Celsius is generally considered too hot for a CPU/GPU.
If your machine gets compromised due to a zero-day vulnerability in Java, of course Java will be the one to blame. There have been a number of such vulnerabilities in the past. That's why many security experts recommend disabling Java: it removes one attack vector.
