The Java EE Platform and EJB specifications currently require the
capability of using RMI-IIOP to export EJB components and to access EJB
components over a network. This requirement enables interoperability
between Java EE products.

It has been suggested that we consider removing the requirement for
such interoperability support from the Java EE Platform and EJB

There are several reasons behind this proposed change:

* RMI/IIOP has been largely superseded by modern web technologies
   that provide interoperability support, such as SOAP and REST.
   Hence, few developers are currently relying on RMI/IIOP for this purpose.
* Implementing the required support is seen as an unnecessary
   burden on Java EE implementors.
* There is a perception that this requirement makes Java EE seem
   heavyweight at a time when we're trying to appeal to developers
   who want a lightweight solution.

Removing this requirement would mean that an implementation of the
Platform would still be required to support remote access to EJBs, but
would not be required to use IIOP to do so. That is, we would be
removing requirements that provide interoperability across products,
but would not be removing requirements that require support for remote
access within a single product, since other protocols could be used.

Further, please note that because Java EE 7 requires support for Java
SE 7, we would also not be removing requirements for the ability to
use the CORBA functionality that is required as a part of Java SE.

If we pursue this direction, the first step, of course, would be to
designate support for RMI-IIOP interoperability as "Proposed Optional".

Please let us know whether you support this proposed change or not.
