In Relation To

Hibernate Search version 5.4.0.CR1 is now available! It was built and tested with Hibernate ORM 5.0.0.CR2, essentially it’s all ready for ORM 5 and we’ll just be waiting for this to be marked Final.

The second candidate release for Hibernate ORM 5.0. CR2 was required because of a bug in how class-loading worked in certain managed JPA environments. The details can be found in HHH-9887. The main changes since CR1 include:

Hibernate Search sends the indexing requests in the post transaction phase. Until now. The JMS backend can now send its indexing requests transactionally with the database changes. Why is that useful? Read on.

Sanne is going to do a virtual JBoss User Group session Tuesday July 14th at 6PM BST / 5PM UTC / 1PM EDT / 10 AM PDT. He is going to talk about Lucene in Java EE.

He will also describe some projects dear to our heart. If you want to know what Hibernate Search, Infinispan bring to the Lucene table and how they use Lucene internally, that’s the event to be in!

Today let’s discuss the interaction between multitenancy and the current session feature.

Multitenancy let’s you isolate Session operations between different tenants. This is useful to create a single application isolating different customers from one another.

The current session feature returns the same session for a given context, typically a (JTA) transaction. This facilitates the one session per view/transaction/conversation pattern and avoids the one session per operation anti-pattern.

When creating a bug report for any project within the Hibernate family, it’s extremely helpful (and, frankly, required) to have an adequate test case available. This is obviously important to make reproducing the issue as easy as possible. But it’s also vital longer-term. Nearly every bug fix should include a regression test, which is frequently based on the original reproducer (sometimes, it’s the reproducer, verbatim).

To help create useful test cases, we’re opening up a repo with various templates. Please see the READMEs in each project’s subdir for more info: Hibernate Test Case Templates

As a starting point, the repo contains two templates for ORM:

Welcome to the newly revamped Hibernate and friends blog.

As you can see, we made it look like hibernate.org and we took the opportunity to clean up the tags to make them more useful. But we had other reasons to migrate.
