[antlr-interest] Nondeterminism problem

[Weida Ma]

I am getting a nondeterminism warning with a parser:

definition
	:	class_decl_or_def | interface_decl_or_def
	;

class_id
	:	"class" IDENTIFIER
	;

class_decl_or_def
	:	(local_qualifier)? class_id
	;

interface_id
	:	"interface" IDENTIFIER
	;

interface_decl_or_def
	:	(local_qualifier)? interface_id
	;

local_qualifier
	:	"local"
	;


SliceB.g:38: warning:nondeterminism between alts 1 and 2 of block upon
SliceB.g:38:     k==1:"local"
SliceB.g:38:     k==2:IDENTIFIER

I think "class" and "interface" should be able to distinguish 
class_decl_or_def and interface_decl_or_def when k == 2. But it seems 
I am wrong? I'd appreciate any help.

Regards,

Weida
