Azul System Tools Libraries Retirement from Containers

Starting with the release of Azul Platform Prime 19.06.0.0, the standard operation mode for Azul Zing Builds of OpenJDK (Zing) in container environments is the non-ZST mode.

Since ZVM 19.07.0.0, the RPM/DEB package dependency towards the ZST package is removed.

As of ZST 5.22.4, the zing-zst-ForContainer packages are empty (zing-zst-8b.ForContainer-VERSION.rpm, zing-zst_8b.ForContainer-VERSION.deb).

Running Zing versions older than 19.06.0.0 in containers with a zing-zst-ForContainer package of 5.22.4 or newer installed will fail with the following error message:

 Zing VM Error: DLERROR: libaznix.so: cannot open shared object file: No such file or directory
Zing VM Error: Please install ZST (Zing System Tools)

The solution for container systems is to upgrade to Azul Platform Prime 19.07.0.0 or newer.
