Yes, Tomcat is a single Java process.

However if you have separate web application deployments, and if Jaybird
is part of the WAR and not deployed within Tomcat itself, then you may
be able to load different embedded libraries per deployed web
application. That has a big caveat though: you will need to specify the
jna.library.path system property per web application, and I'm not sure
that is possible.

However, I forgot about an option: Firebird 3 (and Firebird 3 embedded)
has the option for multiple database engines, for example a Firebird 2.5
engine. However, no such engine is available from Firebird itself. I
know that IBPhoenix has built one that is essentially a Firebird 2.5
engine. You'd need to contact them for more information though, and I'm
not sure if this has additional caveats when loaded with Jaybird.
