I certainly do not read any "not possible" here and do not have any issues
installing several JDKs in parallel, either:
$ /usr/libexec/java_home -V
Matching Java Virtual Machines (5):
9.0.4, x86_64: "Java SE 9.0.4"
/Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home
1.8.0_162, x86_64: "Java SE 8"
/Library/Java/JavaVirtualMachines/jdk1.8.0_162.jdk/Contents/Home
1.7.0_79, x86_64: "Java SE 7"
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home
