CharToByteJIS *ALWAYS* adds ESC-(-B at the end of file

It always add unnecessary escape code at the enf of line.

import java.io.*;

public class JISTest {
  public static void main(String args[]) {
    try {
        OutputStreamWriter osw = new OutputStreamWriter(System.out, "JIS");
        osw.write("test");
        osw.flush();
    } catch(Exception e)
    {}
  }
}
~


result:
test^[(B

ESC-(-B should not be added.
