Access Errors for statically weaved classes in a consuming java module [message #1868826]

Hi all,

recently we stumbled around the following problem when migrating one of our persistence units to eclipselink 4.0.3 and Java 17 using java modules.

The reason for our problem is that for this persistence unit we enabled static weaving and during static weaving our entity get the following tagging interfaces added:

org.eclipse.persistence.internal.weaving.PersistenceWeaved;
org.eclipse.persistence.internal.weaving.PersistenceWeavedChangeTracking;
org.eclipse.persistence.internal.weaving.PersistenceWeavedFetchGroups;

and its corresponding package org.eclipse.persistence.internal.weaving
is not exported by the corresponding module org.eclipse.persistence.core.

It is only exported to org.eclipse.persistence.jpa

But I'm wondering how any java module which refers such a statically weaved entity would ever compile (or run) because these weaved entities could not be loaded . You get errors like these:

cannot access org.eclipse.persistence.internal.weaving.PersistenceWeaved
[ERROR] class file for org.eclipse.persistence.internal.weaving.PersistenceWeaved not found

The only workaround I could come up with is to add a JVM parameter
--add-exports org.eclipse.persistence.core/org.eclipse.persistence.internal.weaving=<module hosting the JPA entities>

which is of course ugly and error prone.

Does anybody has faced this issue as well and is this already addressed in the eclipselink community?

Many thanks and best regards,
Manfred
