classUnknownSymbolException
final class UnknownSymbolException
extends RuntimeExceptionRestricted visibility: declared "@visibility root". Code outside that scope must not name this declaration.
Thrown when a symbol in the AST is neither a rule name nor a declared token.
The AST is read from a grammar file this package generated from upstream source, so a symbol nothing declares says the file and the parser that wrote it disagree. That is a condition of the input, not a mistake in the code reading it, so it is reported rather than declared.
