Hey all, my first post  ,

Anyway, today I finally downloaded the JDK 1.5 and compiled a 2d game engine that I've worked on for the past few weeks. Now while compiling I got several "Note: unchecked or unsae operations" in reguard to the add method of java.util.LinkedList. I assume this has to do with the new Generic types. Also I noticed a big framerate drop from my previous compiles.

The point I want to raise is what suggestions do people have for porting 2d graphics code between 1.4.x and 1.5 . I've seen use of the System.nanoTime() method that apparently works better (I'm just using System.getCurrentMillis() ). Also are there any java 2D optimizations techniques new to 1.5?

Thanks
