> Key: LUCENE-6584
> URL: https://issues.apache.org/jira/browse/LUCENE-6584
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/analysis
> Affects Versions: 4.10.4
> Reporter: Trejkaz
> Priority: Minor
>
> The following test shows that the behaviour of StandardTokenizer differs once
> you start passing Version.LUCENE_4_7_0 or greater:
> {code}
> import java.io.StringReader;
> import org.apache.lucene.analysis.TokenStream;
> import org.apache.lucene.analysis.standard.StandardTokenizer;
> import org.apache.lucene.util.Version;
> import org.junit.Test;
> import static org.hamcrest.Matchers.is;
> import static org.junit.Assert.assertThat;
> public class TestStandardTokenizerStandalone
> {
> @Test
> public void testLucene4_6_1() throws Exception
> {
> doTest(Version.LUCENE_4_6_1);
> }
> @Test
> public void testLucene4_7_0() throws Exception
> {
> doTest(Version.LUCENE_4_7_0);
> }
> public void doTest(Version version) throws Exception
> {
> try (TokenStream stream = new StandardTokenizer(version, new
> StringReader(makeLongString(2550))))
> {
> stream.reset();
> assertThat(stream.incrementToken(), is(false));
> }
> }
> private String makeLongString(int length)
> {
> StringBuilder builder = new StringBuilder(length);
> for (int i = 0; i < length; i++)
> {
> builder.append('x');
> }
> return builder.toString();
> }
> }
> {code}
> However, the Javadoc only mentions the behaviour changes in versions 3.1 and
> 3.4.
> The constructor for passing the version is deprecated, presumably under the
> false impression that no changes occurred during Lucene 4. I know the Version
> parameter was killed off entirely in version 5, which presumably means that
> people who tokenised stuff in Lucene 4.6 or earlier have now been trapped and
> have to copy the tokeniser from Lucene 4 to keep their queries working.
