Which java version?

If you use yum to install opennms, it will pull a copy of java from
the opennms repository due to the jdk requirement.   However, 'runjava
-s' finds the version in your path, which will be openjdk if you have
installed that from your linux distribution.

Does it matter which one is used?

On Centos 6.3, the relevant versions are:
(stock)
java -version
java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.3) (rhel-1.48.1.11.3.el6_2-x86_64)

(From Opennms repo)
/usr/java/latest/bin/java -version
java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)
