I'm thinking that this works in C# because C# does not have statically
enforced exception specifications (I could be wrong... I know very
little about C#). In Java an attempt to throw OperationCanceledException
from a method invoked inside a rule will cause the parser to fail to
compile because the parser methods don't declare that exception in their
exception specifications.
