There are a variety of JDK vendors. We test with the Azul JDK 11. Our only known requirement beyond JDK11 is that tomcat's https should recognize contemporary root certificates.
The following procedure installs Java JDK and verifies its version. If your Linux distribution provides another way to install a JDK - a package manager like yum or apt-get for example - please consult those steps as they may offer better integration with the base operating system.
sudo yum install zulu-11 java -version
