Runtime.exec does not work well on Linux using Japanese character.

Platform : RedHat Linux 6.2J update
jdk : 1.3.1ea-b01

Step to reproduce:
1. login on KDE and locale is ja_JP.eucJP
2. Install jdk1.3.1 for linux
3. Extract attached test1.tar
                    test2.tar
4. sh T01/unix_test.sh
      and T02/unix_test.sh

Result: no response.
        Any Exception is not thrown and any error message is not displayed.
        (seems to stop ?)

This phenominon occurs only on linux with jdk1.3.1.
This program works fine with jdk1.3.0.

I attached two files include the result of trase using strace command.
(One is with jdk1.3.1, the other is with jdk1.3.0)

Please see attached file.
