[epp-dev] JustJ JRE for AArch64

[Ed Merks <ed.merks@xxxxxxxxx>]

I see that the EPP packages now include aarch64 variants:

  https://www.eclipse.org/downloads/packages/release/2020-12/m1

The Java 15 JDK also supports aarch64:

https://download.java.net/java/GA/jdk15.0.1/51f4f36ad4ef43e39d0dfdbaf6549e32/9/GPL/openjdk-15.0.1_linux-aarch64_bin.tar.gz

This Bugzilla asks JustJ to provide support for aarch64:

  https://bugs.eclipse.org/bugs/show_bug.cgi?id=566640

Without that support, the aarch64 EPP packages that include a JustJ JRE 
will not actually contain a fragment with an actual JRE.

Making this work primarily involves making this script work natively on 
aarch64:

https://git.eclipse.org/c/justj/justj.git/tree/releng/org.eclipse.justj.releng/build-jre.sh

But I cannot test how to implement that locally.

Ultimately the JustJ ci instance will need yet another dedicated 
agent/executor:

  https://ci.eclipse.org/justj/

I don't see any mention of aarch64 here:

  https://wiki.eclipse.org/CBI#What.27s_provided.3F

An additional dedicated agent costs one "resource pack", so I will need 
to hunt down someone to donate yet another resource pack.

The two current dedicated agents (for MacOS and Windows) are sponsored 
by Deutsches Zentrum fuer Luft- und Raumfahrt:

Assuming such an agent type exists, I've asked for one:

  https://bugs.eclipse.org/bugs/show_bug.cgi?id=568233

But the more fundamental question is, does anyone care?  And even more 
fundamentally, does any one care enough to contribute?  I don't actually 
personally care about aarch64.
