[hibernate-dev] Analysis of hibernate-release-4.3.6 dependency on JDK-Internal APIs

[Emmanuel Bernard]

Hi,

Three of these errors are related to Infinispan which you have already contacted.
Two are related to dom4j which we use for XML parsing. While I think our next gen version will no longer use dom4j, we don’t plan on moving away from dom4j for the older and current releases. So I am not sure why you guys are removing org.relaxng form the JDK but if you do then we won’t be able to have Hibernate ORM running on JDK 9.
