It's also good because you will be able to easily monitor and manage the
DB threads via a web interface if you'd like.

>I like 2. because I understand it is bad to open new threads in Tomcat.

You understand incorrectly.  It's not bad to start new threads in
tomcat.  It's bad to start badly-written threads.  When you use your own
threads, either make them daemons or make sure they terminate properly
when your webapp shuts down.

The performance overhead of creating and running 7 threads is negligible
on a modern machine and JVM.
