Converting Docx4j to pdf via documents4j

Question

java code to generate the conversion of word to pdf

package com.sonakshi;
import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;
import org.apache.commons.io.output.ByteArrayOutputStream;

import java.io.*;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.Future;
import java.util.concurrent.TimeUnit;

public class Hello{
    public static void main(String[] args) throws IOException, ExecutionException, InterruptedException {
        ByteArrayOutputStream bo = new ByteArrayOutputStream();

        InputStream in = new BufferedInputStream(new FileInputStream("//home//sonakshi_user//Documents//WordDocToConvert.docx"));
        IConverter converter = LocalConverter.builder()
                .baseFolder(new File("//home//sonakshi_user//Documents//"))
                .workerPool(20, 25, 2, TimeUnit.SECONDS)
                .processTimeout(5, TimeUnit.SECONDS).build();

        Future<Boolean> conversion = converter
                .convert(in).as(DocumentType.MS_WORD)
                .to(bo).as(DocumentType.PDF)
                .prioritizeWith(1000) // optional
                .schedule();
        conversion.get();
        try (OutputStream outputStream = new FileOutputStream("//home//sonakshi_user//Documents//Output.pdf")) {
            bo.writeTo(outputStream);
        } catch (IOException e) {
            e.printStackTrace();
        }
        in.close();
        bo.close();
    }
}

I am getting this below exception generated while conversion
