If that judge is your trial judge, it could mean a lot. More likely than not a judge involved in the mediation will not be the trial judge, and therefore an angry judge doesn't mean a thing --- unless the angry judge put angry notes in the file. The Judge was more than likely ticked off because he felt he was providing you with good advice, that you were not willing to accept.
