Daniel Sun commented on GROOVY-8085:
------------------------------------

Since L1 has not been covered by exception table, so exception occurred in the the normal excution flow can not be handled, i.e. no error in the inner try block but failed in the finally block.

I tried to add 99 / 0 to the inner try block to make it fail on purpose, then the exception can be handled properly. I guess some bug exists in StatementWriter(https://github.com/apache/groovy/blob/master/src/main/org/codehaus/groovy/classgen/asm/StatementWriter.java#L308), the range of try block seems not be recorded correctly...

{code}
    public static void main(String[] args) {
        try { 
            try { 
                System.out.println("try!!!");
                99 / 0 
            } finally { 
                99 / 0 
            }
        } catch (Exception e) { 
            System.out.println("catch!!!"); 
        }
    }
{code}

>    Affects Versions: 2.4.8
>         Environment: linux

> I would expect the following code to print `caughtt`:
> ```
> groovy -e 'try { try { true; } finally { 1 / 0 } } catch (e) { println "caughtt" }'
> ```
> But instead, it prints:
> ```
> Caught: java.lang.ArithmeticException: Division by zero
> java.lang.ArithmeticException: Division by zero
>         at script_from_command_line.run(script_from_command_line:1)
> ```
> Why is the exception, thrown by the `finally`, not being caught by the outer try/catch?
