What is a `StackOverflowError` in Java and how does it relate to the event loop?

A `StackOverflowError` in Java occurs when the call stack exceeds its maximum size. This typically happens due to infinite recursion, where a method calls itself repeatedly without a proper base case to terminate the recursion. While Java doesn't have a traditional 'event loop' like JavaScript, the concept applies when dealing with asynchronous operations or threads. If an asynchronous task or thread triggers infinite recursion, it can lead to a `StackOverflowError` that isn't immediately apparent in the main thread, making debugging challenging.
