Java 7 compatibility status

Does anyone know what this is? Is it officially supported?
I'm thinking of upgrading to 7 only with no trace of 6 since they officially discontinued it in Feb. I'm looking for an official response please,
I've only found a bunch of threads of how Java 7 Update (whatever) broke it :/

Serviio 1.2.1 works fine with Java 7 update 17 (i.e. the latest). I have the 64 bit version installed.

It works with 7. Sometimes the Java installation screws something up, so if you have any problems, uninstall all Java and install Java 7 from scratch.
