Dear Apache Tomcat mailinglist, I hope this message finds you well.
I am working on a version upgrade project on larger codebase project that involves several applications interacting with each other. Most applications are today running on Apache 9 with Java 8. We are planning it as a multi-step upgrade: Phase 1 is a short term upgrade: Step 1: Upgrade the Java environment on Apache Tomcat 9.0.111 to Java 25 and the currently built applications as they are(most built with Java 8) Step 2: Upgrade the applications to the same Java version as Tomcat use, in this case Java 25 Phase 2 is a long term upgrade, and will be a larger project since it requires to move away from javax servlets: Upgrade to latest Apache Therefore I am evaluating the compatibility of Apache Tomcat 9.0.111 with Java 25, and I have a few questions I would appreciate your guidance on: 1. Is it possible to run Tomcat 9.0.111 with Java 25? If so, are there any known issues or special configurations required? 2. Can I deploy and run an application built with Java 8, on Tomcat 9.0.111 running on Java 25? If compatibility issues exist, could you please advise on how to address them? 3. If the above configurations are not supported, would it be possible to clarify the specific supported Java versions for different Tomcat versions, with to from and to version of Java, on the official website? A more detailed version matrix would be very helpful for developers. Thank you in advance for your time and assistance. I look forward to your response.
