Now, 1.5 years later and with the release of JDK8 getting closer, I'm 
just curious on how the IcedTea project is doing with JDK8. I've been 
skimming this list and I haven't seen any references to JDK8, but I'm 
not sure what that means.

Have you started any IcedTea support for JDK8, or did it actually end up 
with IcedTea not being needed for JDK8? Is the new build system of any help?
