Object inlining, aka object fusing

Hi all,

this is perhaps not the right place for questions related to object
memory layout in HotSpot, but I dare to ask anyway given the tremendous
expertise about this JVM internals by the Graal developers reading this

Some years ago, Christian Wimmer and Hanspeter Mössenböck conducted
research on object inlining
(http://www.ssw.uni-linz.ac.at/Research/Projects/JVM/AOI.html) and
experimented the idea in HotSpot.

Anybody knows whether their code managed to be officially integrated in
the stock HotSpot VM, and thus also in the JVMCI extended version used
by Truffle/Graal?
