Examples of MalformedServerReplyException

org.apache.commons.net.MalformedServerReplyException
This exception is used to indicate that the reply from a server could not be interpreted. Most of the NetComponents classes attempt to be as lenient as possible when receiving server replies. Many server implementations deviate from IETF protocol specifications, making it necessary to be as flexible as possible. However, there will be certain situations where it is not possible to continue an operation because the server reply could not be interpreted in a meaningful manner. In these cases, a MalformedServerReplyException should be thrown.
