Installation of 17.3 GA
During installation, the java version laid down by 17.0 - SDM installer will install java 1.8 first and the later it would upgrade java to the latest supported version
CommonInstaller uses the version of java on the DVD in the java folder,
In Service Management 17.3GA it's java 11
The installer installs 17.0 SDM then runs setupmdb with the JAVA version laid down by SDM, in 17.0 it's Java 1.8
Runs pdm_configure with the JAVA version laid down by SDM, in 17.0 it's Java 1.8
CommonInstaller installs 17.3 and installs Java 11.
Then setupmdb is run as a post install step using the java laid by 17.3 installer, Java 11
It runs pdm_configure as a post install step using the java laid by 17.3 installer, Java 11.
