Antonio,

Thanks for your input, as to all the others before.
Sorry I mostly replied in the CDI thread, but a lot of it related to either
CDI or other annotations.

If certain ways to "sharpen" how e.g. WARs can do things currently the
domain of EAR can be done without breaking existing functionality and
features that is a good suggestion, but honestly, it feels more PaaS
friendly, so probably best to do some of these things right and carefully
(without the rush that introduced e.g. some of the bugs, SE7 currently
struggles with, though it has no real impact to EE in most cases;-)

Logging, I would personally prefer a real JSR for it if enough people like
you feel the need and pain. There are a few JSRs, Money probably another
good example, that cater to SE, but by their nature will have greater
impact in the Enterprise world. 310 another example. Take BeanValidation,
JSF or JDBC, you name it, they all use java.util.Date or Calendar.
Not all may be immediately changed to new types from these new JSRs, but
some sure will benefit. If JDBC or JPA work more towards non Relational
Databases, too, mapping or binding a Money type sure makes sense, too. With
limitations it also does for RDBs.

I'd see some of those like JSR 330 which via CDI became more important to
EE, than in most Desktop or Mobile use cases, too.
If you get a proper Logging JSR similar to what SLF4J does in many cases,
then this certainly won't make it into EE7, I highly doubt, it makes sense
in SE8 either, given without proper Modularity you can't throw out the old
stuff, same goes for 310, too btw;-)
However I am very confident, some of those make great sense in EE8,
especially with the PaaS focus, where an abstraction of logging ideally per
tenant would come handy.

At my current client we also have to do that, with more than one container
btw. Most of it by tweaking Log4J or other internally used loggers the
right way. So if an abstraction that works similar in different containers
existed, that would simplify not just how we provision our Private Cloud
there.
