Yes.

There may not be one unique runtime approach, but

to pass the TCK running a Java 8 SE?
Nop. That's not the only one dev process.
Today the devs use local JDK8 and devops use JDK11. There is
no one unique process you may think of.
If a user is expecting a EE release to
support Java SE 8 that is what they will be using for
the runtime.The TCK has to pass while running with Java
SE 8 I would say.
In my understanding the compiler
version should be 1.8+ but the runtime JRE should be
11+ due to the reliability of the container.
Hmmm...
We
stated that Compatible Impls MUST support Java
SE 11, but they MAY also
support Java SE 8. Isn't that very similar to
stating that Compatible
Impls MUST support EJBs, but they MAY also
support BMP and CMP Beans? I
was assuming that the Java SE 8 optional
requirement would be part of the
Platform spec. Especially since we also
indicated that the APIs need
to be compiled at the Java SE 8 level.
If
we're saying
that the Compatible Implementation doesn't have
to support the optional
pieces, then that will need to be discussed and
resolved at the Spec Committee.
If
this is just
a TCK requirement, then what would we state in
the Platform Spec?
This
is an especially
pertinent discussion now that the support for Java
SE 8 has been extended to 2030...

I agree I'm not
sure whether the
release plan meant it to be a formally a spec
item.

support for Jakarta EE 9
I believe we agreed that JDK 8 support is
optional for Jakarta EE 9.
I believe we also agreed that one of the
Compatible Implementations submitted
with the specification approval MUST support
all optional features.
I think this means that GlassFish is required
to support JDK 8 and JDK
11.
Or is some other project planning to be the
first Compatible Implementation?
I don't have a problem with allowing others to
support JDK 8 and JDK 11
if they want to, but I fear it's going to be a
fair amount of work for
GlassFish, and requires a commitment from
every component that contributes
to GlassFish.
I'm wondering if we can instead handle this as
some sort of TCK compatibility
rule instead of including it in the spec?
That's not as clean, but it would remove the
spec requirement and thus
allow GlassFish to support only JDK 11 if
that's what it wants to do.
