This is how JRuby has survived for years. A classloader-per-class has
a big memory load (ClassLoader has a lot of internal state, classes
have a lot of metadata) but with permgen bumped up (or replaced with
metaspace as in 8) and a few reuse tricks, it hasn't been a major
issue for u

Charlie,
Truffle is such a general-purpose automatic specialization mechanism that works
like you say via just writing Java code and without a need to use invokedynamic
and without a need to dynamically generate bytecodes.

As I said (many times) before, the methodhandles/indy should be built using
a minimal interpreter supported calling convention:
invoke (that can box/unbox at runtime)
All methodhandles should then be written as static bytecode working with
objects (no dynamic generation of specialized bytecode) s
Regarding indy dense code:
It is certainly a problem both for JRuby with indy and Nashorn with indy that
indy scalability is so bad in 9 builds with the current JITs. I suspect that as
Java 8 grows as a code base and as a language, it will turn into a problem with
Java 8 lambdas too. Nashorn ge

afaik you can set how many times a lambda form has to be executed before it
