] | Within the methods, the variable names are lost.
Java is a stack based machine, and so a method that looks like
```
public int add(int first, int second) {
int sum = first + second;
return sum;
}
```
is going to lose the naming of sum in bytecode that roughly reads as

There is no way in Java to look at the stack and extract variables or any values declared in stacked method stack frames. |

That said, I have to admit I've been looking for a way to inspect the variables on the stack trace, too :). It may be a stupid idea, but it's also an interesting one.
