Subject [jira] Updated: (HARMONY-6336) ArrayIndexOutOfBoundsException thrown without index information; generally AIOBE is thrown without specifiying the index.
Date Mon, 07 Sep 2009 09:09:57 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-6336?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tim Ellison updated HARMONY-6336:
---------------------------------

      Priority: Minor  (was: Major)
    Issue Type: Improvement  (was: Bug)

I agree that it would be more helpful to include messages when throwing the exceptions.

The case you give is a VM/JIT issue, though I also see lots of places in the class libraries
where the exception is being thrown without a useful message.

I'll start to do some tidy up.  Expect it to take a few commits to get a reasonable coverage
done.

> Following code:
>     public static void main(String[] arg) throws Exception {
>         int a[] = {1,2,3};
>         a[3] = 4;
>     }
> Generates 
> java.lang.ArrayIndexOutOfBoundsException 
> in Harmony but 
> java.lang.ArrayIndexOutOfBoundsException 3
> with Sun Java 1.4
> A quick search of the class library shows that ArrayIndexOutOfBoundsException is frequently
called without providing the index.
> This makes debugging index problems very much harder that it ought to be.
