xia0c updated OPENNLP-1286:
---------------------------
     Attachment: pt-leis.bin
    Description: 
When I try to upgrade Opennlp-tools from 1.7.0 to the version after 1.8.0. The following code breaks.

{code:java}
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.nio.file.Paths;

import org.junit.Test;

import opennlp.tools.doccat.DoccatModel;
import opennlp.tools.doccat.DocumentCategorizerME;

public class TestOpenNLP {
		
	@Test
	public void demo() throws FileNotFoundException {
		classify("test");
	}
	
	public void classify(String summary) throws FileNotFoundException {
		
		
		String bin = "/pt-leis.bin";
		InputStream inputStrean = null;
		try {		
			inputStrean = new FileInputStream(Paths.get(bin).toFile());
			DoccatModel doccatModel = new DoccatModel(inputStrean);
			DocumentCategorizerME myCategorizer = new DocumentCategorizerME(doccatModel);
			double[] outcomes = myCategorizer.categorize(summary);
			String category = myCategorizer.getBestCategory(outcomes);
			} catch (IOException e) {
				System.out.println(e);
		} 
	}
}
{code}

The code should pass, but it throws an error:
{code:java}
incompatible types: java.lang.String cannot be converted to java.lang.String[]
{code}
