I believe the java vector assumes a certain possible subset of the cases - specifically the java vector assumes the typeIds are the ordinal value of the enum MinorType. If the java class is consuming an union vector that happens to using ordinal value of enum MinorType for typeIds (for instance, a union vector produced by java) then it would work. Otherwise it would not work. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
