John, Remi, thank you both for your replies! Now, I sadly don't exactly understand what that means: > "doing a Lookup.findVirtual on MethodHandle.invokeGeneric." I first do something such as MethodHandles.lookup().find[Virtual|Static] and the return is a method handle, which I am using to do (let's say) invokeVarargs (as in my "benchmark" code).
And how "MethodHandles.spreadArguments()" could be useful to me, I have to figure out first ;) May I ask, when the next merge of fresh code of MLVM (into the JDK7 mainline) could occur?
