[antlr-interest] Help with compile errors in generated source

[hanasaki jiji]

Hello all... I plugged antlr into maven and ran in netbeans 6.7 and
the source produced is generating compile errors as below.  Any
thoughts as to what is the cause and resolution?  The grammar is the
JSON grammar downloaded from the antlr site.

Thanks,
