The annoying thing is that Java 8 is the only currently supported version of the language. The glacial development speed somehow still manages to deprecate versions faster than they fall out of use.
While Java 8 is the only version that is freely supported from Oracle, it is still possible to buy commercial support for older versions of Oracle's Java platform.
The speed at which they stop freely supporting older versions feels much like a way to squeeze big, slow moving organizations for support contracts.
