Right you are! My value class needed to be marked as Serializable, then it worked fine. Value classes are really weird things in Scala. Sometimes the compiler simply replaces them with the types they wrap, Long in this case. Other times an object is generated. Apparently the upSince field simply got compiled as a Long, hence no problem, while the PosixDate in the Map was resolved to a class--one not serializable so it was not making the trip over the wire. Marked it as Serializable and everything worked.
