I'm upgrading a service from Tomcat 7 -> Tomcat 8, and I'm encountering this issue just now that I'm kinda at a loss for.
Here is the stack trace:

I know that the whole "URL []" and "context with name [{1}]" looks bad, but I don't know why, or how these values were set the way they were. Can anyone please point me in the right direction as to what's going on?
