There's a quite serious memory leak, affecting ALL VERSIONS OF MINECRAFT as far as i know. the memory usage increases, and suddenly decreases. This is a symptom of a memory leak. example: memory usage increases to over 90% and then suddenly decreased to 50% or less........ this is bad, especially for low spec pc's. i will try to upload a file so show the problem

What you describe isn't a memory leak. Memory leaks imply memory is being allocated, and not released. The behaviour you describe is normal, due to the JVM's garbage collection.
