Difference between jaxb-runtime(glassfish) and jaxb-ri(com.sun) and JPMS

[xmourgues]

Hello,

I'm having an issue with this different package :
org.glassfish.jaxb:jaxb-xjc:4.0.4
com.sun.xml.bind:jaxb-xjc:4.0.4

The issue is the following.
I'm using org.eclipse.persistence.moxy which need jaxb-xjc.

If I set up my dependency (and module-info.java just to force loading the xjc module) to use the glassfish implementation. I have the following errors

Module org.eclipse.persistence.moxy does not read a module that exports com.sun.tools.xjc

When I use the com.sun implementation, there is no problem.

I want to use the glassfish because my module which use moxy will be required by a bigger project that already have the glassfish implementation and I can not switch it.

When debugging JPMS module resolution, this doesn't give more information except the module name changing
(extract with glassfish):

...
java.lang.module.ResolutionException: Module org.eclipse.persistence.moxy does not read a module that exports com.sun.tools.xjc

(same extract with com.sun):

com.example.moxy.moxy.xjc.example requires com.sun.tools.xjc file:///home/xmourgues/.m2/repository/com/sun/xml/bind/jaxb-xjc/4.0.4/jaxb-xjc-4.0.4.jar

...

I tried adding --add-reads org.eclipse.persistence.moxy=org.glassfish.jaxb.xjc but it doesnt fix the issue

Here is a repository with a minimal test to reproduce : https://github.com/xmourgues/moxy-xjc-example
All you have to do is switch dependency in the pom.xml and change the requires in the module-info.java

Any help is welcomed

Thanks !
