Description

HivePasrser.g can not be extended anymore as adding any more tokens leads to a "code too large" problem, because the compiled code size would exceed 65536 bytes. The real solution would be to introduce anltr4, in the meantime it can be fixed be moving the tokenNames variable into a separate file.
