Question

I test exceptions using in java an dobjective-C programs.

In these tests, I see a difference in the way of finally block is reached when an exception is catched and rethrown.

Here my java test :

    try {
        Boolean bThrow = true;
        System.out.println("try : before exception sent");
        if (bThrow) {
            throw new Exception();
        }
        System.out.println("try : after sent");
    }
    catch (Exception e) {
        System.out.println("catch, rethrow");
        throw e;
    }
    finally {
        System.out.println("finally");
    }

which displays :

try: before exception sent
catch, rethrow
finally

And here my objective-c test :

    @try {
        NSException *myexc = [NSException exceptionWithName:@"exceptionTest" reason:@"exceptionTest" userInfo:nil];
        BOOL bThrow = YES;
        NSLog(@"try : before exception sent");
        if (bThrow) {
            @throw myexc;
        }
        NSLog(@"try : after sent");
    }
    @catch (Exception *exception) {
        NSLog(@"catch, rethrow");
        @throw exception;
    }
    @finally {
        NSLog(@"finally");
    }

which displays :

try: before exception sent
catch, rethrown
*** Terminating app

Code in finally block is not reached !

Why this difference ?

[EDIT] Sorry, @try … @try … @try… was a mistake.
I changed it, but the problem is the same, i can’t reach finally block in objective-c test

Answer 1

OK, i solved my problem.

In my objective-c test, application crashed, that’s why finally block was not reached.

If I add a try catch block in the main, now in my function, finally block is reached !

So, I confirm that finally block is still reached whatever an excpetion occurs (and is rethrown) or not).
