Tomcat gives errors on startup and shutdown

[andrew_50]

I am running Jasper Server 7.8 on ubuntu 20.04.2 (64 bit), with openjdk 8

Starting tomcat up gives a bunch of warnings (but everything runs, tomcat and jasper server) - tomcat status is running/ok

Stopping tomcat gives a bunch of errors, but does stop.

I have attached a copy of catalina.out

 

Colour me unamused.

Hoping someone will be able to offer me some insight/wisdom/correction.

 

My tomcat.service file is as follows:
