I would like to ask about any plans of speed improvements to
"System.identityHashCode" or "IdentityHashMap"
I use EclipseLink and it uses IdentityHashMap for storing entities
and their clones.
In my case System.identityHashCode consumes 54% of time during insert
data to database. There are lots of other project using
IdentityHashMap and identityHashCode.
CR 6378256 seems to cover this for the client/C1 compiler. Presumably
the server/C2 compiler already intrinsifies the method. It's been in
"fix understood" for a couple of years...
