hi, there will be a grammatical problem when pmml with probability. It works fine to get rid of the parentheses.

FAILED: SemanticException java.lang.IllegalArgumentException: Error: : expected at the position 28 of 'struct<label:int,probability(0):double,probability(1):double>' but '(' is found.

Reopened as a reminder to take a look at this again when the JPMML-Evaluator has been updated with "soft rename" functionality (plus some other relevant API niceties).
