If this was April 1st, I'd be sure that this was satire, but as it is, I'm not sure:
Java SE - Change in Version Numbering scheme in March 2013
In case this vanishes off the web, here's the gist:
Seriously? I don't know who is to blame for this loss of sanity. Oracle, you are not so damn important that you need to re-invent this. My understanding is that there is a well-established convention for numbering incremental versions of a product, that allows for such concepts as minor feature releases and bug fix releases.
The scheme is nicely described here on Stack Overflow: How to do version numbers.
What is sad is that back in the Sun days, Java release did follow this numbering convention.
