JasperServer and Tomcat 9 - Unable to rename class file

Question

We have installed JaspserServer 8.1 as a Windows Service with Tomcat 9.0.69 and are receiving multiple errors of the following form when trying to create reports:

Caused by: java.io.IOException: Unable to rename class file from [D:\JAS\apache-tomcat\work\Catalina\localhost\jasperserver-pro\org\apache\jsp\WEB_002INF\jsp\modules\addResource\reportStep3State.classtmp] to [D:\JAS\apache-tomcat\work\Catalina\localhost\jasperserver-pro\org\apache\jsp\WEB_002INF\jsp\modules\addResource\reportStep3State_jsp.class]

For background, a Windows administrator account performed the installation.

We have already tried changing the Log On account type from Local Service to Local System and restarted the service as described here...

...as well as setting the permissions on the entire JAS directory through right-click -> properties -> unchecking the partially selected "Read-only" checkbox.

We have other tomcat 9 web apps running on the same host (and drive) without issues. Their service accounts are Local System as well.

Wondering what we might be overlooking in our setup.

Thanks!
