Hi, I recently upgraded Struts from version 2.3.34 to 2.5.20. After doing the recommended fixes the application runs correctly but an exception started happening sporadically.
The app is built and runs in JDK 8 with Tomcat 9.0.12 The app is a little big so i have not able to create an example yet. The more relevant libraries in use are Spring + Struts + Hibernate Any tips about how to find the root cause of the issue?
