What’s new in the May beta?

  • JMS 2.0 Currently provides support for JMS 2.0 simplified API to send and receive messages to the Liberty embedded messaging provider so that you can write JMS applications more quickly and easily, using fewer APIs. Also provides support for shared durable and non-durable subscriptions with the Liberty embedded messaging provider so that multiple consumers can connect to the same subscription point but only one of them receives the message.
  • JPA 2.1 Liberty’s JPA 2.1 support is now provided via EclipseLink. This current EclipseLink delivery does not support container-managed UNSYNCHRONIZED Persistence Contexts. Note that EclipseLink’s L2 data cache is currently enabled by default, which is different from OpenJPA’s default behavior.
  • bean validation 1.1 Currently provides method parameter and return value validation, similar to the field/property validation in Bean Validation 1.0. This is most beneficial to use in interceptors before invoking a method in an EJB or CDI managed bean.
  • JSON-P 1.0 Support for JSR 353: Java API for JSON Processing; required JSR for the Java EE 7 platform. Provides a standardized API library for the processing (parsing, generating, searching, and modifying) of JavaScript Object Notation (JSON). Why use JSON instead of XML, and therefore need something like JSON-P?
  • EJB 3.2 Lite You can now configure stateful session beans to indicate they are not capable of being passivated. This is useful for beans that reference objects that have state that cannot be serialized/deserialized.

What’s already in there?

All kinds of lovely stuff, like Servlet 3.1, OpenID Connect, Java 8 toleration, WebSockets, a facelift for the Liberty Repository… Go take a look at the April betas announcement for a full list.
