I'm not sure the Java-centric packages are a great target.  For real Java development most people will want an SDK I imagine.   E.g., a src.zip seems important and not present in a JRE, at least as generated by default by jlink...

That's right.

We'll see when we start adopting it in EPP. Maybe we could try to have JustJ shipping a whole JDK for the case of Java-centric packages.

In principle I think only the src.zip is the missing important part though clearly all the tools like javac are not present either.  The src.zip is 56MB so is rather huge.  The full JDK is on the order of 200MB so also rather humongous...

Anyway, I wouldn't brainstorm too much about it right now as there are still important and enlightening intermediary steps to perform first.

Yes we can communicate more broadly.  An article in the newsletter is forthcoming too.

OK, I think it's better to wait for the newsletter article and then we'll link to it via the @EclipseJavaIDE account. If you think it's better to tweet now, we can also do it, just ask ;)

    No, in combination is probably best.

One of my most significant remaining concerns is the update channel for new versions of the JRE.   I'm not sure we should be putting the JREs in the release train repository, for example..

I imagine EPP could take care of it -at least partly- as it defined the available update sites. We'll discuss that a bit later after 2020-06 is done, when we start playing with JustJ in EPP.

Yes.  When we come up for fresh air will be good.  Of course via touchpoints the JRE installation itself could add updates sites as well...

Other issues that concern me:

1. The fact that Java 11 is LTS so I imagine many people will be most comfortable with that version, not a bleeding edge latest release.
   
2. Perhaps AdoptOpenJDK will become an approved source (which helps with Java 11 LTS), but that presents even more choices of what to put in a package.

    We shall see when we have more time. (I'm moving June 15th, so the
    release timing is terrible for me this year.)
