Can't call method "jar" without a package

[pinate <pinate11@xxxxxxxxx>]

Hi,

We have just installed Auth handler (Apache )  using mod_perl2 and CAS.

1. Initially, we had the  Internal Server Error "Expected token not present", as per these below links suggested this could be because of our invalid cookie format. But for our application to work, we need those cookies

http://stackoverflow.com/questions/8594363/why-am-i-getting-a-expected-token-not-present-in-my-apache-log
http://beutelevision.com/blog2/2012/05/25/quick-fix-for-expected-token-not-present-in-apache2cookie/

So we changed Cookie.pm as seen below

Replace from

    my $jar = $req->jar or return;
    $jar->cookie_class(__PACKAGE__);
    return $jar->get(shift) if @_;
    return wantarray ? %$jar : $jar;

to 

 my $jar = eval {$req->jar()} || $@->jar;             #------------line 42
 eval{$jar->cookie_class(__PACKAGE__)};
 return $jar->get(shift) if @_;
 return wantarray ? %$jar : $jar;

My interpretation of the code in line#42 is if there is some parsing error of cookie, ignore the error and use that cookie  anyway.

2. This fixed the above error, all is working fine in our internal network..we can browse the web 
3. However, when we access the target application from external via vpn and also with some browsers. We are having below

 Can't call method "jar" without a package or object reference at /usr/lib64/perl5/vendor_perl/Apache2/Cookie.pm 

Can someone shed some light into this?

FYI, based on my troubleshooting and investigation
I can see that there is still cookie parsing error executing eval {$req->jar()} in line 42, but somehow $@ is undefined. Hence  calling $@->jar cause such error.

Don't know why it is only failing in certain conditions as explained?  Could anyone suggest some direction or a possible solution?

Thanks

Pinate
