Good morning,
I am getting the following error when trying to start a very generic setup of
Tomcat 10.1.1 on Windows Server 2019.
Error: A JNI error has occurred, please check your installation and
try again Exception in thread "main"
java.lang.UnsupportedClassVersionError:
org/apache/catalina/startup/Bootstrap has been compiled by a more recent
version of the Java Runtime (class file version 55.0), this version of the Java
Runtime only recognizes class file versions up to 52.0

Looks like you are running Tomcat on an older Java, that the app was
compiled with...
Need to lookup the exact class versions, but like:
Compiled with jdk13 and running on java 11.

Is there a minimum version of Java 8 that is required?
Thanks,
