Jan Martin Keil created JENA-2188:
-------------------------------------
Summary: Escape % in TokenizerText#fatal
Key: JENA-2188
URL: https://issues.apache.org/jira/browse/JENA-2188
Project: Apache Jena
Issue Type: Bug
Components: RIOT
Affects Versions: Jena 4.2.0
Reporter: Jan Martin Keil
The presence of "%" near to a syntax error might cause _TokenizerText#fatal_ to
throw an _UnknownFormatConversionException_ instead of a _RiotParseException_.
This happens because of the use of _String#format_ without escaping "%". See
the following example:
{code:java}
import java.io.ByteArrayInputStream;
import static java.nio.charset.StandardCharsets.UTF_8;
import org.apache.jena.rdf.model.ModelFactory;
import org.apache.jena.riot.Lang;
import org.apache.jena.riot.RDFParserBuilder;
import org.junit.jupiter.api.Test;
public class TokenizerTextTest {
@Test
public void fatal() {
RDFParserBuilder.create().source(new
ByteArrayInputStream("<http://example.org/s> <http://example.org/p>
\"example\"@de-DE\" <http://example.org/%D8-graph>" .getBytes(UTF_8)))
.lang(Lang.NQUADS).parse(ModelFactory.createDefaultModel());
}
}{code}
This causes:
