java.lang.OutOfMemoryError: Java heap space

The application attempted to allocate more memory than is available in the Java heap. This can happen due to memory leaks or processing large datasets without sufficient memory allocation.

It broke because the default heap size is insufficient for the application's memory requirements. When the application exceeds this limit, the JVM cannot allocate more memory, resulting in an OutOfMemoryError.

To fix this, you can increase the maximum heap size allocated to the JVM by using the -Xmx option. Additionally, review your code for memory leaks or optimize memory usage.
