> Invocation of String.substring with invalid arguments does not provide the invalid index information
> e.g:
>  -  "HelloWorld".substring(4,1)  on RI gives:  java.lang.StringIndexOutOfBoundsException: String index out of range: -3 
>  -  "HelloWorld".substring(4,1) on Harmony gives:  java.lang.StringIndexOutOfBoundsException with no message, which is less useful
