Can someone tell me what this means?

For starters update java. I'm not exactly sure how high version you can go. Possibly 8u11 at most. Why? Because the latest, java 8 didn't exist when MC 1.7.10 was released.

Edit: Yea, I could have stated better. Currently, there's just a point where java changes so much that old modded MC won't function properly.
