I have an application team that is getting the following stack trace while starting Tomcat 8.5.70. I've done some searching but can't find anything. In looking at their context.xml it appears that they have jmxEnabled="false" in each of the resources.Any assistance would be grand.

If I'm reading https://tomcat.apache.org/tomcat-8.5-doc/jdbc-pool.html#JMX correctly, jmxEnabled has to be true (which is the default).It's a little unclear to me, but then I've not used the DataSource outside of Tomcat.
. . . just my two cents /mde/
