Name: yyT116575 Date: 10/24/2001


java version "1.3.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)


In JAPANESE locale - Swap space/memory usage grows enormously when
setVisible(true) method is called.

Problem :
---------

We are developing / converting a product in JAVA built with AWT components in
JAPANESE locale. While testing our product, we observed that memory usage
(Total VSS column in EnglishResult.txt & JapaneseResult.txt) and Swap space
growing continuously using &#8220;GLANCE&#8221; tool, and it was found that setVisible
(true) (For any component like Frame, Dialog etc.,) method consumes large
amount of memory.

  To ensure this problem, the following &#8220;Operation Memory&#8221; test was carried out
with a sample application in the below mentioned combination of configuration
and platforms.

Java Language : JRE 1.3.1 (Hotspot Client) , JRE 1.2.2 , JRE 1.1.8
Locale : Japanese (ja , ja_JP.PCK , ja_JP.UTF-8 ,
ja_JP.EUCJP , Japanese)
OS : Solaris 8 &#8211; 256 MB RAM , Swap Space 1 GB

Operation Memory:

1. Execute the application
2. Press the &#8220;Show&#8221; button
3. After a dialog is appeared , press the &#8220;Hide&#8221; button
4. Repeat the steps 2 & 3 for 3 times.
5. Repeat step 4 for 3 times.


The data is collected at the following points using GLANCE tool and the result
is shown in EnglishResult.txt (Data of English Locale), JapaneseResult.txt
(Data of Japanese locale).
1. After Step 1
2. After Step 4 ( 3 times)


In the attached result it is found that for every 3 times of opening and
closing the dialog , there is an increase of 1 MB of swap space & Total VSS ,
where as in the original product that we have developed , for every opening and
closing of dialog there is an increase of 7MB ,

We observed the &#8220;memory growing&#8221; behavior in all JRE versions and all Japanese
locales .How ever we attaching data collected only in JRE 1.3.1, ja_JP.EUCJP,
Solaris 8.
using GLANCE tool.
1)ResultJapanese.Txt &#8211; Data collected in Japanese locale
2)ResultEnglish.Txt - Data collected in English Locale

This behavior is NOT observed if the locale is set to English.
Kindly suggest us to overcome the above said problem in JAPANESE locale.

Sample Java Code (Mem.java)
----------------
import java.awt.*;
import java.awt.event.*;
public class mem {
  public static void main(String arg[]) {
    showframe sf = new showframe();
    sf.setSize(300,300);
    sf.show();
  }
}
class showframe extends Frame implements ActionListener {
  Button b1,b2;
  tpframe tpf ;
  showframe() {
    tpf = new tpframe();
    b1 = new Button("show");
    b2 = new Button("hide");
    setLayout(new FlowLayout());
    add(b1);
    add(b2);
    b1.addActionListener(this);
    b2.addActionListener(this);

  }
  public void actionPerformed(ActionEvent ae) {
    if(ae.getSource()==b1) {
      tpf = new tpframe();
      tpf.setVisible(true);
    }
    if(ae.getSource()==b2) {
      tpf.setVisible(false);
    }
  }

}

class tpframe extends Frame {
  TextField tx1,tx2,tx3,tx4 ;
  tpframe() {
    Panel p1 = new Panel();
    Label lb1 = new Label("first tab panel");
    tx1 = new TextField("ONEONE");
    tx2 = new TextField("ONEONE");
    tx3 = new TextField("ONEONE");
    tx4 = new TextField("ONEONE");
    p1.setLayout(new FlowLayout());
    p1.add(lb1);
    p1.add(tx1);
    p1.add(tx2);
    p1.add(tx3);
    p1.add(tx4);
    add(p1,BorderLayout.CENTER);
    setSize(300,300);
  }
}
