How to deal with "java.nio.charset.MalformedInputException: Input length = 1" WSO2 ESB

Some times we are receiving unusual characters in our responses from various back ends. Then WSO2 ESB is facing problems in understanding those characters from the response and it tends to throw following exception.

Most of the case,  by adding following property to the "passthru-http.properties" file will solve the case.

Eg:  once i was getting a response like following

[2015-07-09 12:47:55,236] DEBUG - wire >> "HTTP/1.1 100 Continue[\r][\n]"
[2015-07-09 12:47:55,237] DEBUG - wire >> "[\r][\n]"

[2015-07-09 12:47:55,275] DEBUG - wire >> "[\r][\n]"

Then it thew the above exception.

By adding the above entry as follows, i could get rid of that.
