What causes a memory leak?

These unintentional object references prevent the built-in Java garbage collection mechanism from freeing up the memory consumed by these objects.
What happens when memory leak?
A memory leak reduces the performance of the computer by reducing the amount of available memory. Eventually, in the worst case, too much of the available memory may become allocated and all or part of the system or device stops working correctly, the application fails, or the system slows down vastly due to thrashing.
What is the main cause of memory leaks?
Common causes for these memory leaks are: Excessive session objects. Insertion without deletion into Collection objects. Unbounded caches.
Are memory leaks permanent?
Memory leaks don’t result in physical or permanent damage. Since it’s a software issue, it will slow down the applications or even your whole system. However, a program taking up a lot of RAM space doesn’t always mean its memory is leaking somewhere. The program you’re using may really need that much space.
