Sender AS2 MDN XML Channel error

Hi,

I am trying to configure a sender AS2 adapter to receive asynchronous MDN. But as soon as I create the channel ,it goes in error "Channel configuration is erroneous: java.nio.charset.UnsupportedCharsetException: The target charset iso885915 is not supported".

1. I don't see any other option to configure character set once AS2 MDN transport protocol is selected. Am I missing any configuration?

2. Also I am testing from mendelson and as per the mendelson log MDN is sent to PI system but I do not see any MDN in PI. We are using B2B addon SP1 on PI 7.11.

mendelson log :
