newbie startup question

[Raffaello Giulietti]

Hello,

I'd like to start playing with da Vinci, in particular with the java.dyn
classes (InvokeDynamic, CallSite, MethodHandle, etc.)

They seem to be included in the more recent "Java Platform, Standard
Edition 7 Binary Snapshot Releases" found at
http://download.java.net/jdk7/binaries/. So I'm wondering if they are
complete enough and usable or if I shall build Da Vinci from the
Mercurial repos.

I ask because, currently, I'm only interested in *using* da Vinci rather
than developing for it.

(The build process is not the funniest activity I can think of. I
unsuccessfully tried 3 days on Vista and then finally managed to build
OpenJDK once I switched to an Ubuntu 9.04 guest on VirtualBox/Vista.
BTW, VirtualBox is really cool: great product for a great price ;-))

Thanks for all your kind replies
Raffaello
