DefaultMessageFactory doesn't set the MsgType field when it defaults to creating the Message itself

If there are no version-specific MessageFactory's in the classpath the DefaultMessageFactory will create an empty message. Unfortunately it forgets to set the MsgType which other elements of the QuickFIX/J code rely upon e.g. quickfix.Session. Below is an example stack trace in that situation:

quickfix.FieldNotFound: Field [35] was not found in message.
