If I change the test to (using 1.8.0):

And you tell me that in the first case the call was inlined? That is
unexpected. And if that is the case, then why does this:

the version is a 1.8.0-ea. Since this is a generic way of method
invocation I have to

The arguments have to be reordered, since the MH is a leading argument that
must be deleted (in the case of a DMH). For compiled call

Which version of the jvm are you seeing this problem on, and are you
adapting the method handle every time as well as exact invoking it?
We avoided invoke and invokeExact calls from Java (because they were
sometimes painful to get correct in the case of varargs methods) by having
the fallbacks ret
Hi,
I am currently investigating here some performance issues and I may have
found a culprint here - invokeExact. My case is one where method caching
fails and I will have to do an invokeExact from Java - meaning without
the invokedynamic bytecode and with a non constant method handle. I am
