Description

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
