Java Error: Java12 Shenandoah Garbage Collector Error, How to Handle and Avoid

As one of the most widely used programming languages, Java is widely used in development in many fields. However, various errors and problems may also occur in actual development. Among them, the Shenandoah garbage collector error is the most common in Java development. One of the frequently asked questions.

Shenandoah garbage collector is a low-pause time garbage collector introduced in JDK 12, which can achieve efficient garbage collection without affecting application throughput and response performance. However, in actual operation, the Shenandoah garbage collector may also encounter some problems, such as memory leaks, deadlocks, etc., causing the program to run abnormally or crash.

So, how to deal with and avoid Shenandoah garbage collector errors?

First of all, for the Shenandoah garbage collector error that has occurred, we can handle it through the following steps:

1. Find out the cause of the error: by viewing the Java application log , stack traces and other information to determine the specific cause of the error as much as possible.
2. Check official documentation and community discussions: For different error types, you can check Java official documentation and related community discussions to find solutions and experiences.
3. Update Java version: Try updating your Java version and using a more stable version, you may be able to resolve some Shenandoah garbage collector errors.
4. Modify configuration parameters: According to the error type, appropriately modify Java operating parameters, such as GC logs, heap size, number of concurrent threads, etc., to adjust the performance of the garbage collector.
5. Contact the Java support team: If none of the above methods can solve the problem, you can contact the Java support team for professional help.

In addition to handling Shenandoah garbage collector errors, we can also avoid the occurrence of these errors as much as possible by the following methods:

1. Avoid using unstable versions: whenever possible Use stable Java versions and avoid using immature or unstable new versions to reduce the possibility of errors.
2. Optimize program design: Reasonably optimize program design to avoid a large number of object creation and destruction in the application and reduce the burden on the garbage collector.
3. Reasonable configuration of operating parameters: According to the needs of the application, reasonably configure the operating parameters, such as heap size, number of concurrent threads, GC strategy, etc., to improve the performance of the garbage collector.
4. Check log information regularly: monitor application running logs, check program running status regularly, and detect and handle errors in a timely manner.
5. Reference experience summary: You can obtain sufficient experience and methods by consulting relevant experience documents and community summaries, and improve your ability to handle and avoid errors.

When developing Java applications, the handling and avoidance of Shenandoah garbage collector errors is one of the issues we need to focus on. For developers, it is necessary to continuously learn and master relevant technical knowledge to improve their ability to deal with such errors and ensure the stability and reliability of the program.
