Description Mike Hearn 2023-01-22 22:21:19 UTC
The module-info.class file in tomcat-embed-core-10.1.5.jar isn't valid and gets rejected by tools like jlink. Decompiling it with fernflower shows why:

open module org.apache.tomcat.embed.core {
    requires jakarta.annotation;
    requires jakarta.ejb-api;
    requires jakarta.mail;
    requires jakarta.persistence-api;
    requires jakarta.xml.rpc-api;

Oops. Those Jakarta module names aren't valid Java identifiers. You are apparently synthesizing a module-info.class file without using javac and it results in something that looks like it complies with JPMS but which doesn't.
