Re: [hibernate-dev] Depending on JAXB / JDK11 compatibility
You are right that people will have to add some other dependencies if
they want to use Hibernate on Java 9+, but IMO we should at least put
the dependencies into the pom.xml that we have a hard dependency on
which in this case is the jaxb-api or in module descriptor speak the
"java.xml.bind" module.
People will have to adapt to this and add their own JAXB implementation,
just like they now use Hibernate as JPA implementation.

Hi Christian,
right that's what makes it confusing. We might want to list the
jaxb-api explicitly but it's not enough to make it work: people will
need to know to list several more dependencies.
This is what I've been experimenting with in the Search testsuite
(which uses Hibernate ORM):
<!-- All replacements for JAXB -->
<dependency>
<groupId>javax.xml.bind</groupId>
<artifactId>jaxb-api</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-core</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>javax.activation</groupId>
<artifactId>javax.activation-api</artifactId>
<scope>provided</scope>
</dependency>
I'm afraid that we might as well not list jaxb-api as users need to
understand this all either way.
Thanks,
Sanne
