title: NoClassDefFoundError sun/io/ByteToCharConverter with InterBase JDBC driver
body: <p>With InterClient 7.5.1 and 8.1.5, the creation of a new JDBC connection in Java 8 fails with</p>
  
  <pre><code>java.lang.NoClassDefFoundError: sun/io/ByteToCharConverter
  </code></pre>
  
  <p>This class seems to be referenced or used by the InterClient JDBC library.
  The error does not occur with Java 7. Is there a way to work around this error?</p>
  
  <hr>
  
  <p>This code reproduces the problem on Java 8:</p>
  
  <pre><code>package com.example.so25365952;
  
  import java.sql.DriverManager;
  import java.sql.SQLException;
  import java.util.logging.Level;
  import java.util.logging.Logger;
  
  public class Main {
      interbase.interclient.Connection conn; 
  
      public static void main(String[] args) {
          try {
              Class.forName("interbase.interclient.Driver");           
              DriverManager.getConnection("jdbc:interbase://localhost/data/mydb.gdb", "sysdba", "password123");           
          } catch (ClassNotFoundException | SQLException ex) {
              Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
          }
      }
  }
