The chatter over at Hacker News picks up this: Mysterious Android codebase commit
The discussion goes on for pages and pages, in typical Hacker News style.
The most interesting observation, I think, is this one: This diff is more explicit about what's going on
Change dependency from libart -> libopenjdkjvm.
An article over at VentureBeat offers its own speculation: Google confirms next Android version won’t implement Oracle’s proprietary Java APIs
“As an open-source platform, Android is built upon the collaboration of the open-source community,” a Google spokesperson told VentureBeat. “In our upcoming release of Android, we plan to move Android’s Java language libraries to an OpenJDK-based approach, creating a common code base for developers to build apps and services. Google has long worked with and contributed to the OpenJDK community, and we look forward to making even more contributions to the OpenJDK project in the future.”
I haven't been paying a lot of attention to the case this fall, and I haven't seen a lot of coverage, either, so these random speculations intrigued me, though I have no idea what they mean.
