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

by 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.

WildFly deployments: how to access the (user app) deployment classloader from Hibernate code?

by Sanne Grinovero

It looks like that when Hibernate Search is being bootstrapped in a JPA deployment on WidFly the current context classloader was overriden. That's expected I guess, but it's of a type which surprised me: - org.hibernate.boot.registry.classloading.internal.ClassLoaderServiceImpl$AggregatedClassLoader while I really need to access the deployment classloader; on WildFly this would be a ModularClassloader having a toString of the form: ModuleClassLoader for Module "deployment.DeploymentName:main" from Service Module Loader The ClassLoaderService itself is of no use in this case as it only exposes the same aggregate ClassLoader which is loading Hibernate Search, while I need to get fine-grained access to the ClassLoader which is loading the user deployment. There is no such problem when I start the Hibernate SessionFactory directly (not in a container): in that case the Context Classloader matches the system one so I don't think is being set by Hibernate ORM. If such a semantics is needed in WildFly, could we then expose the original TCCL via an accessor on ClassLoaderService ? Thanks, Sanne

Publishing documentation as rendered by asciidoc

by Sanne Grinovero

Hi all, I would love to publish the documentation the way it looks like from the asciidoc rendering (before the transformations via docbook), as it looks like much more readable. But I'd like to keep our style and branding rather than the default docbook template; did someone already experiment with that? Or could anyone volunteer please as my design skills are better avoided :-) Cheers, Sanne

dehydrate knows acout the Hibernate mapping, disassemble does not.

by Eric J. Van der Velden

Hello, I have to correct my code because I work with a second level cache in the following case (1-N bidirectional). Suppose we have a Container class type, with a Set<Item>, and an Item class type. In the Hibernate mapping we make the Set non-inverse. For persistence of the Item instances we only have to add them to the Container instance's Set, and I do not have to set the Container reference in the Item instance. When an Item is inserted in the database table, the Item-persister.dehydrate method skips the Container reference in the Item instance, and takes the Long which is there because of the BackrefPropertyAccessor$BackrefGetter.getForInsert() method. This will be the foreign key in the row. The Item-persister.getPropertyInsertability()=[true,true,false,true] for example, and the method Item-persister.dehydrate knows about it: The false means: skip the Container reference in the Item instance, and the llast true means: take this number (instead). My question is: Why does the Item-persister.disassemble not take into account the Hibernate mapping? Because it does not, I have to make a correction in my code to set the Container reference in the Item instances, only for the second level cache. Thanks.

Signing up for JIRA

by Gunnar Morling

Hi, In JIRA I'm seeing this permanent message: "Need to file a bug report and don't have an account? Email emmanuel at hibernate dot org with JIRA Account creation as subject. You'll receive an invite by email." So have we abandoned the self sign-up? Why is this, due to spamming issues? Not sure whether it's really a problem, but this may raise the barrier for getting a JIRA account and thus stop some new users from reporting bugs. --Gunnar

[Search] Internship next year

by Guillaume Smet

Hi, Just a heads up: I'm going to propose an internship this year (scholar year more precisely) on Hibernate Search contribution. I'm not sure I'll find the good intern for this but that's the plan. The internship season usually starts in Feb/March in France so it's for early next year. The internship is located in Lyon, France and if you happen to meet a good student interested in it, I'll be glad to meet him. I usually am interested in final year student of French "Grandes Ecoles" as we name it here but brilliant persons in general are welcome :). I have a couple of subjects in mind (like finishing the work I started on plain text search) but I'm sure we'll be able to find good ideas to keep a person busy during several months! -- Guillaume
