However, time has moved on and I was wondering what the testing status and
advice is for more recent JDKs.
Particularly, I'd like to know whether Oracle JDK 8u25 safe for production
use (on centos 7)? We've used JDK 8u20 without issues on our dev servers
but it would be nice to have some guidance on this since we are moving to
production soon with this. The reason we're using Java 8 is because we are
using that for our apps as well and it is kind of nice to have just one jdk
to worry about. Also, I suspect there may be some perfomance benefits given
the amount of change that went into e.g. hotspot.
In general, an overview of common vms and status with respect to
elasticsearch would be nice to have somewhere. There are quite a few
different suppliers of vms at this point and picking one seems to be a bit
of a black art & leap of faith currently. There's Openjdk, oracle jdk,
Azul's Zulu (essentially openjdk as far as I know), and Azul's Zulu
Enterprise. You can get each of these for Java 6, 7, and 8. Especially for
openjdk, it also matters how it was built.
1.7u55 has indeed be the recommended version for a long time, but JDK 8u25
is fine too. The page that you linked is from elasticsearch-hadoop and
might be a bit outdated, we are trying to keep up to date information about
recommended JVMs at the following URL:

Jilles, thanks for the mention. I am the community manager at Azul and am
hoping to be of service if needed...
Yes, our Zulu product is a free certified, Open Source implementation of
Java 8 and OpenJDK which is ready for Linux, Windows, Mac OSx, and Docker.
It is a complete Java SE 8, 7 and 6 compliant JDK & JVM, is free to
download, use, and/or bundle with applications with no licensing
restrictions.
