Does this have any impact on Truffle to speed up Ruby on Rails?

  Nothing technical is changing. It's just a change in the development process used by Oracle. A lot of this announcement will be opaque if you don't know the history of Sun, but suffice it to say that the core Java development process has a lot of oddness in it that exists to make Java more open and less controlled by Sun-then-Oracle, for example if you go look at their mailing lists you'll see they "vote" on whether their own new colleagues should be allowed to commit to the source tree. This is basically legacy stuff these days but if I understand correctly was written into various legal agreements. Anyway, OpenJDK is its own project with its own processes and culture, GraalVM was historically from a totally separate part of Oracle and adopted its own processes and development culture. This announcement doesn't change what tech is available, it's more about re-organizing how development is done. It doesn't really affect Java developers much, except that maybe now more stuff will come out of the box with a 'regular' JDK. Currently to get Graal technology you need to use their own custom spin of the JDK.

    The part I like is that it basically _forces_ GraalVM on everyone who is currently using a JVM with Oracle lineage. It would be not unlike PyPy and CPython agreeing to ship together, not really but kinda. GraalVM is going to see adoption go up > 100x.
