NetBeans 12.6, maven webapp project Maven 3.8.4 Ant 1.10.12 Followed guide at https://tomcat.apache.org/tomcat-10.0-doc/graal.html Sorry in advance if not all issues should be reported here but instead are graalvm native image related, I'm reporting everything here and on their github fro completeness. https://drive.google.com/file/d/17flFW5nlNCdojlvJxCOy23NJBj03p46u/view?usp=sharing In this link you can find a folder with everything I used from tomcat stuffed folder downloaded from the github link present in the tomcat AOT guide, to all commands I put in a script for easier testing purpose, source webapp, built webapp, screenshots, everything :D I'll start by saying I'm well aware I could definitely have overlooked something, anyway I managed to get to the final native image and it works, BUT: If you remove .class files from webapps/webappname folder, when you run the binary file, it won't find those files, only jsps. This is strange because those files are actually present in the fat jar, and this actually beats the purpose of builidng a native image if you have to ship it with java files. If there is a class extending ServletContextListener (InitClass in this webapp), when running command with "--catalina -generateCode" parameter, where you have to access all jsps and servlets, the class extending ServletContextListener will be initialized/used(?) like 2 times, but the second time not completly, resetting everything done in the first initialization. In this webapp it happens when you access the only servlet present. Anyway all code is in the google drive link and in InitClass i put some prints so you can see what I mean. In another bigger webapp my InitClass initializes a lot of things used by the webapp basically screwing it. This issues happens only in this phase becasue in the second phase where the parameter is "useGeneratedCode" it works normally both with this simple test webapp and in my other one When building with native-image command, if "-J--add-exports=java.management/sun.management=ALL-UNNAMED" isn't used as additional parameter, errors will pop on run crashing the app. (screenshot in the google drive link)
