Bug#1108280: tomcat10: tomcat doesn't use `jakartaee-migration-shaded.jar` when installed

[Fab Stz]

Package: tomcat10
Version: 10.1.34-0+deb12u2
Severity: normal

Dear Maintainer,

I'm trying to setup a webapp (css-validator) with the xml file in
/etc/tomcat10/Catalina/localhost/css-validator.xml

Since the webapp still uses the javax.servlet classes, I made use of

<Loader jakartaConverter="TOMCAT" />

so that tomcat automatically converts the class names from javax.servlet to jakarta.servlet

When restarting tomcat10, it fails with ClassNotFoundException: org.apache.tomcat.jakartaee.EESpecProfile

So I installed tomcat-jakartaee-migration package which holds the jar
containing the required class.

This is however not sufficient. I finally had to create a symbolic link in
/usr/share/tomcat10/lib to /usr/share/tomcat-jakartaee-migration/lib/jakartaee-
migration-1.0.6-shaded.jar

Shouldn't this be handled automatically by either tomcat package or tomcat-
jakartaee-migration package? How to proceed otherwise?

I suppose there will be the same issue with tomcat11.

Fab
