This is still an issue for me. I'm using version 1.11.2. Java goes from around 3GB of RAM (even though Minecraft is only allocated 1GB) to 6.6GB in 20-40 seconds. It stays at 6.6GB for 30 seconds and then the RAM usage quickly goes down to 3GB and after that it starts using a lot of RAM again. This happens continuously.
