final class GrammarParseException
extends RuntimeExceptionRestricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.
Reports that grammar source text could not be turned into a grammar.
Bison and Lemon grammars are read from files that ship with the server they describe, so a grammar that declares tokens but no rules, or that ends before its rules section, is a property of the input rather than a defect in the parser. Callers that load grammars at runtime are expected to handle this.
