The father of Java and a longtime Sun Microsystems employee, Gosling left the company once it was acquired by Oracle. In the process, Gosling didn’t pull many punches in his criticism of Oracle and how it was handling the acquisition and integration of Sun technologies.

Here is the complete post from James Gosling’s blog on the topic:

Through some odd twists in the road over the past year, and a tardis encountered along the way, I find myself starting employment at Google today. One of the toughest things about life is making choices. I had a hard time saying “no” to a bunch of other excellent possibilities. I find it odd that this time I’m taking the road more travelled by, but it looks like interesting fun with huge leverage. I don’t know what I’ll be working on. I expect it’ll be a bit of everything, seasoned with a large dose of grumpy curmudgeon.

“Grumpy curmudgeon” is a good way to describe Gosling’s appearance at TheServerSide Java Symposium earlier this month, where he riffed on topics such as Java, cloud computing and social media.

Of course, probably most interesting about this news is that back in August, Oracle sued Google over Google’s use of Java. And now the father of Java is on Google’s side. There has been a lot of speculation around that lawsuit, including the claim that Google will end up owning Java as a result of the lawsuit.
