<div dir="ltr">Hello all,<div>I'm working on getting our IDP from version 3.4.7 ready to move forward to 4.0.1. I've fixed all the deprecated warnings. The OS was ubuntu 16.04LTS and openjdk 8 with Tomcat 8. I ran the in-place upgrade to get me to 18.04 and that upgraded to openjdk11. Tomcat remained the same. The idp.war file deployed and ran as expected. According to the Supported versions for idp4, I must run Tomcat 9. I upgraded to Tomcat 9 and the idp stopped working. There is nothing in the idp-process.log file. The tomcat logs show:</div><div><br></div><div>
