Hello,
I have an application team that is receiving the following exception after 
upgrading to Tomcat 9.0.90.

Exception java.lang.NoClassDefFoundError: 
org/apache/tomcat/dbcp/pool2/BasePooledObjectFactory

If they revert back to 9.0.89 it once again works. Was there a change to this 
component between 89 and 90?

Unused code was removed. That was one of the classes that was removed.

Applications should not be using Tomcat's internal fork of Commons Pool. They should add the Commons Pool JAR to WEB-INF/lib and use it directly.
