## Java, 76 or 31
Counting only the insertions made to the code, ignoring new lines. 76 if you count *everything* I've added, 31 if you exclude the first line and the last line, i.e. only counting `int a=1/0;try{}catch(Error e){}`.
<!-- language: lang-java -->
class P{public static void main(String[]A){
try
{
while(true)
try
{
int a=1/0;try{
}
catch(Exception ex2) { }
}
catch(Exception ex1)
{
// your goal is to reach this catch block by modifying the code ...
// in the inner try block above
// You win if you reach this part and execute on of the following code lines
//Console.WriteLine("You won!"); // for C#
// Or
System.out.println("You won!"); // for Java
}
}catch(Error e){}
}}
