<b>Warning:</b> This operation can be expensive, as it may involve traversing portions of the Java heap. It is primarily intended for debugging purposes and should not be used in performance-critical code.
It's intended to help developers identify object leaks or to validate the number of instances of a specific class during development.
It is the caller's responsibility to do GC if they don't want unreachable objects to get counted.
