Prepare for some really long traces....
Last time I had 10+ frames, but ok, let me check again, maybe something
changed... but I have to use 8u5, since 8u11 and 8u20 are broken for us.
I will use this program:
def foo(x) {
x.each {println it}
}
foo([]) /* 1 */
foo([]) /* 2 */
foo("") /* 3 */
foo("") /* 4 */
And meassure for the each method from the callsite in foo.
So in case 1 we visit the callsite the first time, thus this one is
especially long, since we have the dynamic invocation of the target handle:

that makes then 21 stack frames to get from the call site to my method
selection method in IndyInterface, where the resulting handle is called
and produces another 78 stack frames.
In case 2 we use the cached handle:

makes 55 frames. In case 3 we have a cache miss and it is 34 frames to
get to selectMethod again and 50+ frames from there.... I think I better
stop here.
My first few frames are exactly like what you have:

> rtPbc.r728.invoke(Object printInspectorString:113)
only that it does not stop there by far.
I assume, your amount of frames is what you get when you are able to set
the handle directly in the bootstrap method. We cannot, we have to use
runtime types in most cases.
Since I have already 21 frames to get there kind of (my method selection
method actually) I think I should show what is involved for that.
basically I install this handle mh
> MethodHandle mh = MethodHandles.insertArguments(SELECT_METHOD, 0, mc, sender, name, callID, safeNavigation, thisCall, spreadCall, /*dummy receiver:*/ 1);
> mh = mh.asCollector(Object[].class, type.parameterCount()).
> asType(type);
on a MutableCallSite. There are a lot of parameters there, though we
need those.. mc is the callsite, sender is the class the call originates
from, name, the name of the method, callID defines the type of the call,
which is one of property get, property set, cast, normal method call.
safeNavigation is a flag to skip the method call in case the receiver is
null, thisCall if the call is made using "this" as receiver, spreadCall
if for example the receiver is a list and the call is supposed to be
invoked on all the elements of the list. These are all meta information
we provide through the callsite already. The normal method call
arguments are gobbled up in the asCollector part and given as an
Object[] to the method selection. Oh yes... the receiver is a dummy, to
bypass that limitation of not being able to call anything on null. The
real receiver is then the first argument.
Maybe I am doing something wrong, but should the few lines I posted
really produce that many frames already? Maybe the situation would
already improve if I would make callID, safeNavigation, thisCall,
spreadCall into one int
ah... to show an example where things are much better... when I do 1+1,
I can safe on guards:

That's 15 frames. But it is rare that I can do things like that
