I'm curious if we're looking in the right places and am looking for

an app in this kind of context where you don't have any requests or
responses being generated. TIA
Some wild guesses and what we do to find performance issues:
We have logging with timestamps and SQL query duration logging and
also do quite some log output on these "daemon" processes.
I guess that will help finding the spots where you can than dig
deeper. Also you could check your disk io, VM usage.
About Tomcat: I have no idea whether there is something where you can
get statistics from a deployed app on Tomcat.
Another idea: how is the db behaving when the application gets slow?
What do the statistics there say? What if you connect to the db at
that time and execute similar queries? Any degradation there? Have you
tried closing and re-opening the database channel programmatically?
