three layers model
Dear All
I have java apps running over three tiers model ( Apache - modJK) , Tomcat
8.5.29, and postgress 9.4 cluster with repmgr and pgpool -- all the layers
use same OS Debian 8.10
we are planing to upgrade the OS to 9.5 and also upgrade the tomcat to
version 9 and JDK to version 9
Is there any comparability list for using these components ?

If the JRE runs, Tomcat should run. Barring any dependency issues
(like things being removed from JREs that need to be added-back-in to
support your application), any future JRE should work with any older
Tomcat.
There should really be no compatibility problems with Tomcat and the
JRE. Your application, however, may have some compatibility issues
with those upgrades.
I you find any problems with Java 9 and Tomcat 9, please report them
here. That configuration should certainly be supported.
