When a user input a string and [enter], string+[enter] code in 1.4.2 is different from that in 1.3.1.

 OS : WindowsXP (SP1, Japanese)
 JRE : 1.3.1_16/1.4.2_10

REPRODUCE:
 1) Compile the attached test program, Frame2.java
 2) Invoke "java Frame2"
    A frame whic has 2 text area.
 3) input "a","b","c" and press enter in the upper textarea.
 4) Click "translate" button.

The following results will show up in the lower textarea.

In 1.3.1_16,
length=4
(0x)61
(0x)62
(0x)63
(0x)a

 The difference seems to come from different way for CR.
 "enter" is "\n" In 1.3.1, but in "\r\n" in 1.4.2.
