if you go on a world Java will crash you and one of the things it will say is will say Java Hotspot {TM} 64-Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

*What I expected to happen was it woundn't crash and i wound play on a sever happily

*What actually happened was Java crashed after i just got my username and password and logged in and i was very upset and mad

Steps to Reproduce:
1. press play like how you wound always start Minecraft
2. press play to go to the world screen [duh]
3.press selected world on any world it will spawn you then before you can even move it will crash you
