I have below Perl code where I am executing the java program on remote machine using NET:SSH:Expect. I want java script to be run in background for my requirement but once I exit from the Perl code my java scripts running in background gets automatically killed. Please suggest any solution. 

#!/usr/bin/perl
#use strict refs;
#use warnings;

use Expect;


use Net::SSH::Expect;

my $ssh = Net::SSH::Expect-> new (
        host => "MYHOST",
        password => "user123",
        user => "user123",
        raw_pty => 1,
        log_file => "log_file"  # this line actually got my head spinn
+ing in right direction
);

my $login_output=$ssh->login();

sleep 1;
my $output=$ssh->exec("pwd");
warn "$output\n";
$ssh->exec("/sbin/fuser -k 9090/tcp");
my $output1=$ssh->exec("cd /home/tecnomen/JanusSIM2.0");
warn "$output1\n";
$ssh->exec("javac Atsi2.java");
sleep 1;
warn "starting the ATSI script\n";
my $output3=$ssh->exec("java Atsi2 &");
sleep 10;
warn"$output3\n";
