cant catch a simple exception

[gavvyth...@gmail.com]

I am testing the following code

try{

                

                    JSONParser p = new JSONParser();

                    Map<String, Object> h = p.parseJSON(new InputStreamReader(input));

            

                }

                

                catch(java.lang.ArrayIndexOutOfBoundsException e)

                {

                    System.out.println("Error : " + e.getMessage());

                    return;

                }

the parseJSON() call throws an exception ArrayIndexOutofBounds under some circumstances but I cant catch it! Can anyone advise

[Th3B1gBull]

maybe you'r trying to catch the wrong exception.

ArrayIndexOutOfboBoundsException should be a subcluss of IndexOutofBoundException... try it with catch Exception and look if it works.

thanks for the suggestion but no that does not work either

Is this on the device or in the simulator?  If device, which device?

Its on the simulator. I think I have had enough of codeneme one to be honest , its a great idea and I m sure it will be an awesome product but really its a long way off in my opinion...

This is quite a leap based on just not being able to catch an exception.  If you're running in the simulator, then it's just running on your machines JVM and you're dealing in pure Java.  So if you can't catch an exception, then it's really either that you're doing it wrong or there's a JVM bug.  I wouldn't bet against the JVM on this one.

Do you have a stack trace?

Try putting a print statement just after the parseJSON() call. e.g.

 Map<String, Object> h = p.parseJSON(new InputStreamReader(input));

Log.p("We are here");

My prediction, is that the code will reach your "We are here" print statement.  I suspect that JSONParser is catching the ArrayIndexOutOfBoundsException and printing the stack trace and not propagating it up.  That's why you can't catch the exception.  Because no exception  is actually being raised by parseJSON.  Does that make sense to you?

Ultimately, you'll want to look at the JSON code that you are parsing to see why the parser is choking on it.
