2022-09-22 - Moved this section out of the README file.

I verify the Snap packages by compiling, packaging, testing, running, and linking some very simple Java console, Java Swing, and JavaFX applications on a variety of Linux distributions and architectures.

The following table shows the status of my tests on QEMU virtual machines:

	Arch	Processor	System	Notes
✔	amd64	Intel Core	Fedora 34 Workstation	1
✔	arm64	ARM Cortex-A57	Ubuntu 20.04 LTS
✔	armhf	ARM Cortex-A15	Ubuntu 20.04 LTS
✔	i386	Intel Core	Raspberry Pi Desktop
✔	ppc64el	IBM POWER9	Ubuntu 20.04 LTS
❌	s390x	IBM/S390 2964	Ubuntu 20.04 LTS	2

1. The commands in Snap packages print the following message on Fedora 34 Workstation:
   WARNING: cgroup v2 is not fully supported yet, proceeding with partial confinement.
2. Java crashes on QEMU virtual machines that use the s390x architecture. See QEMU Issue #655.

The following table shows the status of my tests on physical machines:

	Arch	Processor	System	Hardware	Notes
✔	amd64	Intel Xeon E3-1225	Ubuntu 20.04 LTS	Dell Precision Tower 3420
✔	arm64	ARM Cortex-A53	Ubuntu 20.04 LTS	Raspberry Pi 3 Model A+	1
✔	armhf	ARM Cortex-A7	Raspberry Pi OS	Raspberry Pi 2 Model B
✔	i386	Intel Atom N270	Ubuntu 18.04 LTS	Dell Inspiron 1011
✔	ppc64el	IBM POWER9	Ubuntu 20.04 LTS	IBM Power System LC921	2
✔	s390x	IBM/S390 8561	RHEL 8.4	IBM LinuxONE III LT1	3, 4

1. With just 512 MiB of RAM on the Pi 3 Model A+, the jlink and jpackage tools are killed when they run out of memory using a 64-bit OS. The other JDK tools still work.
2. I thank the Open Source Lab at Oregon State University for a node on their IBM POWER9 cluster.
3. I also thank Marist College for a virtual server on their massive IBM LinuxONE mainframe.
4. Java console and Swing applications work, but JavaFX applications fail to start on the IBM LinuxONE. The Prism ES2 pipeline fails in X11GLFactory.java, perhaps because there is no graphics card. The software pipeline, chosen with -Dprism.order=sw, fails at ViewScene.java:78 when it detects the machine's big-endian byte order.
