Static code analysis reveals not fully covered enum in ch.qos.logback.core.subst.Tokenizer

The DEFAULT_VAL_STATE is not being covered in

switch (state)

{ case LITERAL_STATE: addLiteralToken(tokenList, buf); break; case START_STATE: throw new ScanException("Unexpected end of pattern string"); }

return tokenList;
}

Probably not a problem, but I suggest adding a

case DEFAULT_VAL_STATE:
throw new Error("Cannot happen");
break;
