[Stable] Install openjdk-8-jdk safely in Raspbian Buster (Debian 10) environment

１．Introduction

My past article How to install openjdk-8-jdk on Raspbian Buster armhf and How to install openjdk-8-jdk on Debian Buster (Debian 10) armhf procedure required installing an unstable "sid" package, which caused glibc2.29 to be installed without permission. This time I will describe the procedure for installing openjdk-8-jdk without installing the unstable "sid" package and keeping the whole environment correct. The standard glibc for Raspbian Buster (Debian 10) is glibc2.28. Note that openjdk-8-jdk is required to build Bazel.

２．Environment
