According to the API Reference you must retain a session cookie. I cannot see an option to specify a cookie jar in Rest::Client but there is an option to provide a LWP::UserAgent. So you might have to set up a UserAgent with a cookie jar and pass that to Rest::Client. Setting up an agent with cookie support could work like this: 

my $myagent    = LWP::UserAgent->new();
my $cookie_jar = HTTP::Cookies->new(
    autosave       => 1,
    ignore_discard => 1,
    );
$myagent->cookie_jar( $cookie_jar );

Update: I cannot test this but it should look like 

%options = ( "url"      => "j_security_check",
            "j_username" => $username,
            "j_password" => $password,
            "useragent"  => $myagent );

Update 2: The useragent that Rest::Client sets up if you do not provide one can be accessed as well. So it could also work like 

my $cookie_jar = HTTP::Cookies->new(
    autosave       => 1,
    ignore_discard => 1,
    );
$client->getUseragent()->cookie_jar( $cookie_jar );
