Why is a String in Eclipse truncated when requested via a URL?

Question

Java

Hello!
I wanted to process the data contained when received on request through the URL library. But the data is not fully output both to the console and when saved to a file. I can't understand why? I work through Eclipse. I already solved a similar problem, but only on Idea (the trial license ended) the code worked. By the way, when I started the debug (Debug as) I saw that the data comes in full (5000 geo points in the form of a json array). Why is a string truncated when it is assigned to a variable and output to the console? Here is the code itself: (WARNING I use lombok!)

package com.jsonEx.il;

import java.io.BufferedInputStream;
import java.io.BufferedWriter;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class UrlConnection {
    private final String adress;
    private final String PATH;
    private URL url;

    /**
     * Метод получения соединения URL
     * 
     * @return URL
     */
    public URL getUrl() {
        try {
            url = new URL(adress);
            System.out.println(url.toString());
        } catch (MalformedURLException e) {
            System.out.println("Ошибка UrlConnection в getUrl(): " + e);
        }
        return url;
    }
    
    /**
     * Метод получения содержания запроса по url
     *
     * @return String
     */
    public String getJsonString() {
      StringBuffer strB1 = new StringBuffer();
      getUrl();
      try {
        //HttpURLConnection urlcon = (HttpURLConnection) url.openConnection();
        BufferedInputStream bufinstream = new BufferedInputStream(url.openConnection().getInputStream(), 64);
        byte[] bytemas = new byte[64];
        while (bufinstream.available() != 0) {
          bytemas = bufinstream.readAllBytes();
          strB1.append(new String(bytemas, StandardCharsets.UTF_8));
        }
        bufinstream.close();
      } catch (IOException e) {
        System.out.println("Ошибка UrlConnection в getJsonString(): ");
        e.printStackTrace();
      }
      return strB1.toString();
    }
    
    public String saveInFiles(String json) {
        Path path = Paths.get(PATH);
        if (!(Files.exists(path))) {
            try {
                Files.createFile(path);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        
        try(BufferedWriter buffer = Files.newBufferedWriter(path)){
            //для записи в файл
            buffer.write(json);
            
        }catch(IOException e) {
            System.out.println("Ошибка в записи 1");
            e.printStackTrace();
        }
        return json;
    }

}

package com.jsonEx.il;

public class ServiceJson {
    private final static String PATH = "src/main/java/save.txt";
    private static String json;

    public static void main(String[] args) {
        String urlAdress = "https://nominatim.openstreetmap.org/search?state=Samara&country=russia&format=json&polygon_geojson=1";
        String urlAdress2 = "https://shortiki.com/";
        System.out.println("Запуск, содержимоме:");
        UrlConnection url = new UrlConnection(urlAdress, PATH);
        //url.getUrl();
        json = url.getJsonString();
        url.saveInFiles(json);
        System.out.println(json);
    }
}

By the way, if you substitute the urlAdress2 variable, then the data is completely displayed! (html page)
