Package: tomcat9
Version: 9.0.31-1~deb10u4

You may be misinterpreting what you are reading.

Debian (and downstream) maintain stable versions of their packages. Basically, they (Debian, specifically) want a SUPER stable package that admins don't have to worry is going to blow-up on them with what should be minor upgrades. They usually pick a version to go with a major release and then add patches for things like security and ignore the new features, etc. and other things that might change.

This is more difficult with a project like Tomcat which doesn't actually publish patches, but instead publishes new versions. I'm not sure what Raspbian does to upstream packages (probably nothing) or if they are Debian-based or Ubuntu-based. Ubuntu seems to me to be following the unstable branches of everything and less conservative than Debian, for better or worse.

You may find that this bug isn't fixed in your version. You may also find that it won't be fixed until a new (Raspbian) release in the future. That future may take a while.

You could look at the package availability in other branches of Raspbian (or Debian, whichever is appropriate) to see if maybe the unstable branch contains a better version (for you).

You could also just install it yourself from official ASF packages any time.

Tomcat 9 on a raspberry pi 4 (w00t!).

Maybe you are still just waiting around for that tiny CPU to run all
that bytecode.

/snark

Seriously, though, I'd be interested to hear about your pi-based Java
work in another thread. I have 2 Pi 4s and 2 Pi Zeros that I haven't
managed to do anything with besides running EmulationStation (which I
highly recommend for anyone who grew up with an NES. Pew-pew!).
