Re: [jakartaee-platform-dev] Java SE 8 or 11 for Jakarta EE 9?

["Kevin Sutter" <sutter@xxxxxxxxxx>]

Edwin,
I agree that requiring
Java SE 11 as the minimum could be an impact to the application servers.
 We still have many, many customers still running on Java SE 8.  If
app servers move to Java SE 11 as the minimum, you may be alienating a
huge set of potential customers.

Remember, I'm
not saying that app servers can not support Java SE 11.  I'm just
indicating that providing the minimum version as Java SE 8 is more welcoming.

True but think of this. Setting 11 as
the base for JakartaEE 9 compatibility shouldn’t require any technical
changes on the platform for this release.

However it could be a big change voor
vendors and more importantly: end users. Because when 11 is the base level,
this means that Application servers and end users can make use of Java
11 features.

This could provide a fresh new feeling
of building apps with JakartaEE, which is much needed to inspire new developers
on the platform.

Just my thoughts as an end user.

Regards,

Edwin

choice is to keep Java 8 as the minimum as that doesn't affect the functionality
of the JakartaEE 9 release

Since we're trying
to nail down the Jakarta EE 9 content before early December, I'm going
to start a few separate threads to discuss the major topics.

Should Jakarta EE 9 keep Java SE 8 as the minimum, or should we move to
Java SE 11?  

Note, even if we decide to move to Java SE 11 as the minimum, this does
not mean that we will require JPMS.  We're only talking about the
runtime support.  Also, even if we decide to stick with Java SE 8
as the minimum, compatible implementations could support any version of
Java SE 8 and beyond.

Java SE 8 Pros

• Consistent with Java EE 8 and Jakarta EE 8.  Limits migration concerns.
• No need to provide the "missing" Java EE technologies that were removed from Java SE 11.
• Still has a long support cycle (2025?).

Java SE 11 Pros

• Latest and greatest LTS release for Java.

As
you can see, I'm having a tough time justifying the move to Java SE 11
-- especially with all of the required work for Jakarta EE 9, namely the
jakarta namespace change.
