Hi Ram Yelisetty,

It looks like your request content string contains escape character like '%' and your request content string might be something like this "abc% @de".

However, java.net.URLDecoder.decode("String") throws exception for such escape
characters. So Please make sure your request content string does not contain escape charecter(%).
