I believe I found the cause of your problem.
CREATE in CREATE OR REPLACE from the input is parsed as
--> sqlplus_file paser rule
--> create_object paser rule
--> create_package_body paser rule
--> CREATE paser rule
--> CREATE : 'create' ; lexer rule
So 'CREATE' in the input is being matched against 'create' in the lexer
rules which will always fail because upper case 'CREATE' is not lower case
'create'. Since the lexer has no other alternative, you get the error.
Since I have no experience with ANTLR and case sensitive grammars, the only
quick solution I can offer is obviously to make the input match the lexer,
or make the lexer match the input.
If you plan to tackle case sensitive parsing with ANTLR you may find the
following helpful.
You can search the mail for help using http://antlr.markmail.org/ or try
Stack Overflow tags using ANTLR at http://stackoverflow.com/tags.
The grammar does try and support case sensitive keywords, but how successful
I can't say.
