In the post, Josh Bloch says:
Like many of you, every year we look forward to the workshops, conferences and events related to open source software. In our view, these are among the best ways we can engage the community, by sharing our experiences and learning from yours. So we’re sad to announce that we won't be able to present at JavaOne this year. We wish that we could, but Oracle’s recent lawsuit against Google and open source has made it impossible for us to freely share our thoughts about the future of Java and open source generally. This is a painful realization for us, as we've participated in every JavaOne since 2004, and I personally have spoken at all but the first in 1996.
We understand that this may disappoint and inconvenience many of you, but we look forward to presenting at other venues soon. We’re proud to participate in the open source Java community, and look forward to finding additional ways to engage and contribute.

I'm aware of the patent infringement action, but don't remember Oracle suing the open source community. A little whiny.
I have seen Josh speak many times at JavaOne and his talks will definitely be missed. The puzzlers talk was great. I also see that Crazy Bob Lee dropped out in support. A quick twitter search shows a lot of activity.
For the record, I will be at JavaOne.
