Turning on DFA.debug gives the following trace for the decision which is
failing,

  Enter DFA.predict for decision 47
  DFA 47 state 0 LA(1)=\uffff(-1), index=1
  min[0]=5
  max[0]=d
  eot[0]=-1
  eof[0]=-1
  1 -1 1 -1 -1 -1 1 1 1 -1 -1 -1 -1 -1 -1 -1 -1 -1 1 -1 1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 9 

also, DFA47.eof == [-1, -1, -1, -1, -1, -1, -1, -1, -1, -1], if that's
relevant.


Is there any more info I could provide?
