I am using Java on a UAV project, and have been told that it is often not used when designing military UAVs due to safety concerns. Why is this? I know it has something to do with the fact that it generates it's own code, but can anyone with knowledge of UAVs go into a little more detail about this?
It is inherently inconsistent for speed.
As it uses it's own garbage collector it is inevitable that when GC kicks in the rest of the system must slow down a little to accommodate it. Because of that you cannot guarantee the timeliness of your code.
Don't get me wrong - this is not a critique of Java - I am just saying that in Java you cannot guarantee that a certain piece of code will always run within a certain amount of time.
