Linda/all,
I wanted to run this by you, as Linda's "fear" she expressed last week at
the JCP EC Meeting that Spec Lead or EG Members of Java Batch (JSR 352)
argue, they wish to keep redundancies to Java 7 (AutoCloseable) for the
sake of backward-compatibility with some old JVMs, and EE Containers and a
JDK, which is scheduled for Sun-down this February.
What is your oppinion on that? I was under the impression, the idea of
"Simplification" and "Harmonization" for EE 7 wants to address exactly
cases like that, or would you prefer it to duplicate things that the
Platform (SE7/EE7) already defined elsewhere?
I remember, other EC Members, Oracle and Red Hat primarily expressed
discomfort with some aspects of JSR 352 being incompatible with Java EE 7.
That is clearly another one, regardless if those members spotted it earlier
or not.
Thanks and Regards,
--

Subject: [Bug 4518] Both ItemReader and ItemWriter should extend
AutoCloseable

I would argue that, as Chris brought up in his original response to this
issue,
the AutoClosable interface would be of limited (at best) usefulness for an
ItemReader or ItemWriter. As he points out, the open and close methods are
not
called as part of the public API, and even if it was, there isn't a concrete
association with an ItemReader/ItemWriter with a resource. It could be
accessing a file, a database, a method on an object, a web service, etc.
The
coupling of this to a resource like this doesn't make sense to me.
However, the cost of adding it and changing the required JDK version to 1.7
is
huge IMHO. I'd vote for not implementing this interface and keeping the JDK
requirement at 1.6.
