    • Ease-of-use: Declarative security using CDI, notification of timed events using CDI event and observer mechanism
    • Infrastructure for cloud support: Configuration of multiple tenants, simplified and improved security configuration; and REST-based APIs for monitoring and management
    • Alignment with Java SE 8: Repeating annotations, lambda expressions, Date/Time API, Type annotations, Completable features, etc.
    • Candidate JSRs: JCache, JSON-B, Java Configuration
    • Web Profile: JSON-B will likely be included
    • Pruning: JBLocalHome) and support for CORBA IIOP interoperability
  • CDI 2.0 (Jul 1, 2014) @cdispec, JSR 365
    • Split CDI into two parts: Core CDI programming model and Java EE integrations for CDI
    • Define a portable bootstrap API for CDI
    • Overhal thread-bound request-response context model, allow the application or container to portably push the active context to CDI when it requires the use of CDI
    • Introduce modularity to CDI, CDI 2.0 Modularity Proposal
    • Define a lightweight container
  • MVC 1.0 (Aug 19, 2014) JSR 371
    • Leverage existing Java EE technologies
    • Model part should leverage CDI and Bean Validation
    • View part should leverage existing view technologies like JSPs and Facelets
    • Controller could be either JAX-RS based, invent a new technology, or defined a technology-independent way of definining
    • Out of scope to define a new templating language, existing language should be evaluated, possibly define an SPI for additional ones to be integrated
  • JSON Binding (Jul 14, 2014) JSR 367
    • Standard way to convert JSON into Java objects and vice versa.
    • JSON-B will leverage JSON-P and provide a conversion layer above it.
    • A default mapping algorithm will be defined for converting existing Java classes to JSON. The default mappings can be customized through the use of Java annotations and will be leveraged by the JSON-B runtime to convert Java objects to/from JSON.
    • Requirements from upper layers of JAX-RS
    • JSON-B will have a similar feel to JAXB
  • Servlet 4.0 (Jul 22, 2014) @servlet_specJSR 369
    • Expose support for the upcoming IETF standard HTTP/2 to users of the Servlet API
      • Request/response multiplexing
      • Stream prioritization
      • Server push
      • Upgrade from HTTP 1.1
    • Refresh the Servlet API with to achieve compliance with new features in
      HTTP 1.1
    • Responding to community input
  • JAX-RS 2.1 (Aug 19, 2014) JSR 370
    • Adding support for Server-Sent Events
    • Improving integration with CDI
    • Exploring support for non-blocking I/O in providers (filters, interceptors, etc)
    • Evaluating ways in which declarative security can be supported either directly in this JSR or by leveraging other EE-platform JSRs
    • Making JAXB conditional on runtimes where it is available
    • Providing integration with JSON-B
    • Building upon the hypermedia API added in version 2.0
    • Investigate the reactive programming paradigm as a way to improve the JAX-RS asynchronous client API
    • Evaluating any requirements necessary to support the use of JAX-RS resource classes as as controllers in the MVC 1.0 JSR
  • JSF 2.3 (Jul 21, 2014) @jsf_spec, JSR 372
    • Ajax method invocation: Allows invoking CDI managed bean methods directly from Ajax, all owing the response to be sent using standard JSON
    • Community input: multi-field validation, @Inject FacesContext, EL
      performance optimizations, and cross-form Ajax clarifications
    • Better integration with Java EE 8 and Java SE 8
  • JMS 2.1 - Draft 1 (Jul 7, 2014) @jms_spec, JSR 368
    • Simplifying and extending the API required to receive messages asynchronously
    • Portability of JMS providers within Java EE servers will be improved
    • Clarify “application server facilities” in chapter 11 of JMS 2.0
    • Clarify JCA resource adapater relationship
    • Improvements in JMS provider in Java EE transaction
    • Corrections and minor enhancements

JSR TBD
