[jira] Commented: (HARMONY-997) String.replaceAll method does not work like RI if replacement string contains a backslash

["Nathan Beyer (JIRA)" <ji...@apache.org>]

    [ http://issues.apache.org/jira/browse/HARMONY-997?page=comments#action_12424453 ] 
            
Nathan Beyer commented on HARMONY-997:
--------------------------------------

Do you have some documentation or code to assert that this is a bug in Harmony and not a bug in the RI? Based on my quick read of the API, it would seem that doing a replacement with a '\' character, if properly escaped should work. Even if it's not meant to, then a StringIndexOutOfBoundsException seems like a weird error.

In any case, the underlying difference is in the regex module, so any further examples should be expressed with the underlying APIs.

Thanks.

> This test:

> produces different  results when runned on Harmony or RI
> RI fails with a message:
> Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 1

>         at java.util.regex.Matcher.appendReplacement(Matcher.java:696)

> I think this is Harmony bug.
