> Doesn't look they implement Serializable. CommonTree doesn't know anything about it's tokens, it may hold tokens which are not Serializable. I don't know where can someone ever want to have such tokens, but maybe there is such a case. Supply one if you can.

You have to create CommonTree which restricts the type of the token it holds, something like SerializableCommonTree. There is CommonToken which is already Serializable and could be used as a restriction on `Token token` attribute of the CommonTree class. To this letter I've attached an implementation that I've tried to make and which doesn't work due to the problem described in the second question here: [ http://www.antlr.org/pipermail/antlr-interest/2006-July/016831.html ]. Feel free to make use of it.
