References: In-Reply-To: Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-Virus-Checked: Checked by ClamAV on apache.org Thanks Mahadev / Flavio for the pointers.

Curious , does this warrant a jira to consolidate the discussion to keep in one place ? I had been trying to gather bits and pieces from various sources .
