Open Web Start - java.sql.date ClassNotFound when lauching the client

Question

We are currently migrating from Java 8 to Java 17 + open web start. We are facing an issue we are not able to solve after quite a lot of research : We get a ClassNotFound error on java.sql.Date when launching the client. The package is present in the module.java file.

Here is the complete stack

We checked the the module.java file, added the add-opens=java.base/java.lang=ALL-UNNAMED, but no result

Has somebody had this issue before?

Does your project have a `module-info.java`? If so, does it contain `requires java.sql;`? — Mark Rotteveel, Nov 25 '22 at 16:23
Yes we did. Here's the content of the file :requires kernel.remote; requires commons.collections; requires cre.icu4j; requires jasperreports; requires java.datatransfer; requires java.desktop; requires java.logging; requires java.management; requires java.naming; requires java.prefs; requires java.rmi; requires java.sql; requires javafx.base; requires javafx.controls; requires javafx.graphics; requires javafx.swing; requires javafx.web; requires javafx.fxml; requires javafx.media; requires jcs; requires jdk.jsobject; .. — oslodev, Nov 25 '22 at 18:07
My experience with the Java Module System is limited, but have you tried adding add-opens=java.sql/java.sql=java.rmi — Mark Rotteveel, Nov 26 '22 at 07:54
Hello, thanks for your reply. We tried this : ``and this `` with no result (same error) — oslodev, Nov 28 '22 at 10:58
