    Dear Professor:
    When I checkpoint  a  java program I encounter some problems. Now I list the steps:
    Program code:
    public class Hello {
            public static void main(String[] args) {
                    // TODO Auto-generated method stub
                    for(int i=0;i<=220000;i++){
                            System.out.println(i);
                    }
            }
    }
     
    Step1
    #cr_run java Hello
    The program is running correctly……..
    Step2
    [root@localhost ~]# ps -a
      PID TTY          TIME CMD
    31746 pts/4    00:00:01 java
    31756 pts/5    00:00:00 ps
    Step3:
    [root@localhost ~]# cr_checkpoint 31746
    [root@localhost ~]# ls
    -a  anaconda-ks.cfg  context.31746  Desktop  install.log  install.log.syslog  test.c
    Step4:(some errors ,restart  failed)
    [root@localhost ~]# cr_restart context.31746 
    - open('/tmp/hsperfdata_root/31746', 0x2) failed: -2
    - mmap failed: /tmp/hsperfdata_root/31746
    - thaw_threads returned error, aborting. -2
    - thaw_threads returned error, aborting. -2
    - thaw_threads returned error, aborting. -2
    - thaw_threads returned error, aborting. -2

    - thaw_threads returned error, aborting. -2
    - thaw_threads returned error, aborting. -2
    - thaw_threads returned error, aborting. -2
    Restart failed: No such file or directory
    But when I checkpoint a C program it can be correctly restarted.
    Can you help me resolve this problem ?
    Thank you very much !
