java.sql.SQLException: GC overhead limit exceeded

This exception is thrown when the Java Virtual Machine (JVM) has exhausted all available memory and has failed to recover memory through garbage collection.
The garbage collector is responsible for freeing up memory that is no longer being used by the application. When the garbage collector is unable to reclaim enough memory, the JVM throws the GC overhead limit exceeded error.
This error typically occurs when the application is running low on memory or has a memory leak. A memory leak occurs when the application fails to release memory that is no longer needed, causing the JVM to run out of memory.
To fix this error, you can try the following solutions:
1. Increase the heap size of the JVM by setting the -Xmx parameter to a higher value.
2. Optimize your code to use less memory, for instance by reducing the number of objects created or by using more efficient data structures.
3. Identify and fix any memory leaks in your code.
4. Use a memory profiler tool to analyze your application's memory usage and identify any areas that need optimization.
5. Consider upgrading to a newer version of Java that has better memory management capabilities.
