I am very new to AEM. I have an environment where AEM 6.3 is installed. I am unable to open the Maintenance page for the author node at "http://x.y.z.w:4502/libs/granite/operations/content/maintenance.html " .
Below are some excerpts of the error in the error logs.

What could be the approach needed to resolve this?
I have the same issue but i only encountered this after i have installed the SP2 package. Is there anyone had encountered the same issue?
