Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded

This error occurs when the Java Virtual Machine (JVM) is spending too much time on garbage collection (GC) and is unable to free up enough memory. When this happens, the JVM throws an OutOfMemoryError with the message "GC overhead limit exceeded".

The GC overhead limit is a threshold that specifies the maximum percentage of time that the JVM can spend on garbage collection before it is considered excessive. By default, this limit is set to 98%, which means that if the JVM spends more than 98% of its time on garbage collection, it will throw an OutOfMemoryError.

To resolve this issue, you can try one or more of the following:

1. Increase the heap size: This error can occur when the JVM is running out of memory. You can increase the heap size using the -Xmx option. For example, you can set the heap size to 2GB by adding the following to your command line: -Xmx2g.

2. Reduce the amount of memory used by your application: If your application is using too much memory, you can try reducing the amount of memory it uses. This can be done by optimizing your code, reducing the amount of data stored in memory, or using more efficient data structures.

3. Tune the garbage collector: You can tune the garbage collector to better suit your application's needs. This can be done by adjusting the GC algorithms, the heap size, and other parameters.

4. Use a profiler: You can use a profiler to identify memory leaks and other performance issues in your application. A profiler can help you identify which parts of your code are causing the JVM to spend too much time on garbage collection.
