my biggest request: allow the call of a super constructor (like 
super(foo,bar)) using MethodHandles an have it understood by the JVM 
like a normal super constructor call... same for this(...)

Because what we currently do is annoying and a major pita, plus it 
bloats the bytecode we have to produce. And let us better not talk about 
speed or the that small verifier change that made our hack unusable in 
several java update versions for 7 and 8.

This has been denied in the past because of security reasons... And 
given that we need dynamic argument types to determine the constructor 
to be called, and since that we have to do a call from the runtime in 
the uncached case, I fully understand why this is not done... just... it 
would be nice to have a solution that does not require us doing 
basically a big switch table with several invokespecial calls

bye Jochen
