Java error on first page load

I get this when I load my page up for the first time. I'm not certain what the error is from. I am only seeing this since I updated to 7.2 from 7.1.

The problem with my issue was an out of date version of Tomcat or Apache or some other system within the file directory below the appserver folder but above the ROOT directory.

I made a clean install of yellowfin and copied the Appserver directory to my prod, and then replaced the contents of ROOT. My header was fixed, as was all java issues.

Thanks for trying Yellowfin
