Sockets created by the
com.sun.corba.se.impl.transport.DefaultSocketFactoryImpl factory can be
affected by firewalls if that connection is left idle for long periods
of time. (closed out). A workaround for such an issue could be to have a
simple corba thread send some simple ping traffic on the socket at
scheduled intervals. That may not be possible for legacy applications.
Proposed solution is to add an implementation specific system property
flag which would have the keepAlive feature turned on for sockets
returned by the CORBA DefaultSocketFactoryImpl class. The application is
then in a better position to manage the keepAlive settings via the OS.
This had been fixed in Java SE 6 and I'm looking to port the new
property to jdk7u & jdk8.
