Strange Oracle JDBC Driver error on Application Deployment
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.

Host-wide Singleton Instance
I am adding a redis implementation (jedis) to my application. I have a jedis implementation class that holds the connection pool and interfaces with jedis. That class needs to be instantiated once per host and then referenced from that point on by all of the webapps in the host. Is there an 'architected/correct' way to set this up?
