[Building Sakai] SakaiSigning ClassCastException

[Branden Visser]

Hi all,

Just yesterday, we noticed that one of the servers in our cluster 
started giving a HTTP 500 error [1] when one of our external tools would 
try and authenticate. After a reboot of the server this morning, it's 
"fixed".

Has anyone else experienced this, or know what could have caused it?

Thanks,
Branden
