IdHashShardingStrategy fails after 1.7M id is generated
-------------------------------------------------------

          Key: HSEARCH-237
          URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-237
        Project: Hibernate Search
      Issue Type: Bug
  Affects Versions: 3.0.0.GA
       Reporter: Rafal Glowacz


public class IdShardingStrategyTest extends TestCase
{

  private IdHashShardingStrategy _defaultIdStrategy;
  private IdShardingStrategy _idStrategy;

  protected void setUp() throws Exception {
    _idStrategy = new IdShardingStrategy();
    _idStrategy.initialize(null, createDirectoryProviders());
    _defaultIdStrategy = new IdHashShardingStrategy();
    _defaultIdStrategy.initialize(null, createDirectoryProviders());
  }

  private DirectoryProvider[] createDirectoryProviders() {
    return new DirectoryProvider[]{new MockDirectoryProvider(),
                         new MockDirectoryProvider(),
                         new MockDirectoryProvider()};
  }

  public void testIdSharding() {
    long id = 1;
    long limit = 1000 * 1000000 * 1000000L;
    try {
       while (id < limit) {
          generateForAddition(_idStrategy, id);
          generateForDeletion(_idStrategy, id);
          id += 129653153;
       }
    } catch (Exception e) {
       fail("Couldn't get directory for id " + id);
    }
  }

  public void testIdHashSharding() {
    long id = 1;
    long limit = 1000 * 1000000 * 1000000L;
    try {
       while (id < limit) {
          generateForAddition(_defaultIdStrategy, id);
          generateForDeletion(_defaultIdStrategy, id);
          id += 129653153;
       }
       fail("Should fail with ArrayIndexOutOfBoundsException for long id");
    } catch (Exception e) {
    }
  }

  private MockDirectoryProvider generateForAddition(IndexShardingStrategy strategy, long id) {
    return (MockDirectoryProvider) strategy.getDirectoryProviderForAddition(null, id, id + "", null);
  }

  private DirectoryProvider[] generateForDeletion(IndexShardingStrategy strategy, long id) {
    return strategy.getDirectoryProvidersForDeletion(null, id, id + "");
  }

}

Workaround:

Returned value is minus for id's bigger then 1.7M so for time being I added check like: return value < 0 ? -1 * value : value; Works fine for me.
