Thank you for the comments. To avoid excessive trial and error, is it possible to provide a combination of tested versions that ensure default Tomcat examples running in native image without error? Could you please indicate the version of Tomcat, GraalVM(EE or CE), JDK, maven, ant? I want to use these specific versions you pointed to make sure default Tomcat examples will run normally in term of native image without additional customization. Thank you in advance.
