Всем доброго времени суток, в програме есть два потоки, один читает, с одного файла, второй записывает транслитный текс во второй, выкидает ошибку source not found, вот исходные класы, почему она появляется? вот исходный код класов:
Главный:

package mypackage;

import java.io.IOException;

public class MainClass {
    public static void main(final String...args) throws IOException {
        new CreateFiles();
        final ThreadBuffer tb = new ThreadBuffer();
        new Thread() {
            public void run() {
                if(!tb.isInterrupt()){
                    try {
                        tb.readString();
                    } catch (InterruptedException ie) {                   
                    } catch (IOException ioe) {} 
                } else {
                    this.interrupt();
                    try {
                        tb.closeFiles();
                    } catch (IOException ioe) {}
                }
            }
        }.start();
        
        new Thread() {
            public void run() {
                if(!tb.isInterrupt()){
                    try {
                        tb.putString();
                    } catch (InterruptedException ie) {
                        
                    } catch (IOException e) {
                    }
                } else { 
                    this.interrupt();
                }
            }
        }.start();
    }
}

Промежуточный клас-буфер:

    public boolean isInterrupt() {

    }

    public long getFLength() {
        return fLength;
    }

    public void setFLength() throws IOException {
        fLength = rafToRead.length();
    }

    public void setRafToRead() throws IOException {

        notify();
    }
   
    synchronized public void readString() throws InterruptedException, IOException {

                if (td.isTransChar(chArr[count])) {
                    chArr[count] = td.getTransChar(chArr[count]);
                }
            }
            tempCh = "";
            for (char ch : chArr) {
                tempCh += ch;
            }
            tString = tempCh;

            else {
            interruptFlag = true;
        }            
    }

}

Хеш таблица для транслита:

package mypackage;
import java.util.Hashtable;

public class TranslitDictionary {
    private Hashtable<Character, Character> translitHt;
    public Character getTransChar(Character ch) {
        return translitHt.get(ch);
    }
    public boolean isTransChar(Character ch) {
        return translitHt.containsKey(ch);
    }
    public TranslitDictionary() {
        // TODO Auto-generated constructor stub
        translitHt = new Hashtable<Character, Character>();
        translitHt.put('А', 'A');
        translitHt.put('Б', 'B');
        translitHt.put('В', 'V');
        translitHt.put('Г', 'G');
        translitHt.put('Д', 'D');
        translitHt.put('Ж', 'G');
        translitHt.put('З', 'Z');
        translitHt.put('И', 'I');
        translitHt.put('Й', 'J');
        translitHt.put('К', 'K');
        translitHt.put('Л', 'L');
        translitHt.put('М', 'M');
        translitHt.put('Н', 'N');
        translitHt.put('О', 'O');
        translitHt.put('П', 'P');
        translitHt.put('Р', 'R');
        translitHt.put('С', 'S');
        translitHt.put('У', 'U');
        translitHt.put('Ф', 'F');
        translitHt.put('Х', 'H');
        translitHt.put('Ц', 'C');
        translitHt.put('Ч', '4');
        translitHt.put('Ш', '4');
        translitHt.put('Щ', '4');
        translitHt.put('Є', 'E');
        translitHt.put('Ю', 'U');
        translitHt.put('Я', 'J');
    }
}

и создание файлов:

package mypackage;

import java.io.File;
import java.io.RandomAccessFile;
import java.io.IOException;

public class CreateFiles {
    CreateFiles() throws IOException {
        File f1 = new File("C:\\testfile.txt");
        if (!f1.exists()) {
            f1.createNewFile();
        } else {
            f1.delete();
            f1.createNewFile();
        }
        File fT = new File("C:\\translitedFile.txt");
        if (!fT.exists()) {
            fT.createNewFile();
        } else {
            fT.delete();
            fT.createNewFile();
        }
        RandomAccessFile raf = new RandomAccessFile(f1, "rw");
        raf.writeUTF("Здание аеропорта");
        raf.close();
    }
}

Все исправил, работает
