Yes, I think pretty much everything in recent Linux distributions is aimed at making it more single-user and PC-like instead of a unix server. Following Apple's lead, I guess. But even a single user may need to run applications with differing requirements. Fortunately you can still set JAVA_HOME and give a full path to either executable - you just have to follow the weird symlinks or list the paths from the rpm to figure out where they really put things.
setting JAVA_HOME generally isn't required for running java at the shell, just putting the right java bin directory first in the path is sufficient...
when you invoke java, it sets JAVA_HOME itself if its not already set.
and, WOW, what a tangled web of symlinks.
export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.65-2.5.1.2.el7_0.x86_64/jre export PATH=$JAVA_HOME/bin:$PATH
is the REAL java directory... but that will change with a minor update. yuck!!!
