[antlr-interest] throws on rule declaration being ignored

I have a tree parser that's doing semantic analysis on the AST generated by my
parser. It has a rule declared as follows:
transitionDefinition throws WorkflowStateNotFoundException: /* ... */
This compiles just fine and matches the rule syntax at
http://www.antlr.org/wiki/display/ANTLR3/Grammars but my exception is never
declared so the Java compiler complains.
./tool/src/main/antlr3/org/antlr/grammar/v3/ANTLRv3.g shows that it's building
a tree (but I'm not actually positive if it's the v2 or v3 grammar that ANTLR
3.2 is using):
throwsSpec
: 'throws' id ( ',' id )* -> ^('throws' id+)
;
I know I can make it a runtime exception, but I'd like to use my exception
hierarchy. Am I doing something wrong or should that syntax work?
Thanks.
