To accompany the rumored renewal of affections between Brad and Jen, eWeek is reporting a thaw in the chill between Hibernate and Spring:

Despite an often tense relationship between leaders in their respective open-source communities, the Spring and JBoss leaders are now talking about a truce.

Rod Johnson, chief executive of Interface21, the company that maintains the Spring Framework, told eWEEK that he would welcome an opportunity to work with JBoss. Johnson spoke with eWEEK just weeks after JBoss leader Marc Fleury told eWEEK he was open to working with the Spring community in some fashion.

The apparent thaw in the often chilly relationship could signal a big boon to Java developers who use the Spring Framework with JBoss’ Hibernate technology. Spring is a lightweight Java application framework that helps developers avoid the complexity of the Java 2 Platform Enterprise Edition (J2EE), while Hibernate is an object/relational persistence and query service for Java.

Reporting the conflict from the frontlines was Jobster’s senior war correspondant Scott Haug: 

The height of the friction between the two camps was perhaps best captured in a blog post from last year by Scott Haug, a developer at Jobster, entitled “Hibernate Hates Spring.”

However, many developers who posted comments to Haug’s post said they use both Spring and Hibernate, and many called for a truce.
