JOPA 0.9.11 Released

The latest version of JOPA - 0.9.11 - has just been released into Maven central. The most notable changes are:


  • Finished implementation of support for result set mapping - EntityResult (Feature #7).
  • Fixed issue with PostLoad lifecycle callbacks and listeners not being called for referenced entities (Bug #10).
  • Improved performance of the getter/setter Aspect. This also caused smaller memory requirements for tracking persistence context of entities.
  • Rewrote persistence provider discovery to work the same as in JPA.
  • Better support of the `isLoaded` methods.
