We do quite a bit of Java development and particularly with regards to Java EE 7. In the past I've had bad experiences in terms of a stable Java environment on production servers on FreeBSD.
It appears that OpenJDK is the best option on FreeBSD right now - but is it something one can trust as much as Oracle's Java on Linux?
These are mission critical servers, so I would hesitate to take chances. To put it in perspective, even the latest Java 8 has a serious bug (on Linux) that we've recently reported to Oracle, so we'd like to be as risk averse as possible.
You can also install and use the Linux version of Oracle Java on FreeBSD. The FreeBSD Foundation and Oracle also started a project to build/distribute binary packages of OpenJDK for FreeBSD this year.
