Martin,
I'll accept your adding of the comment as a solution to my suggested
improvement.
charlie ...
P.S. I sense you did not like my feedback / comments, or were somehow
offended. I was trying to offer you a suggestion to improve to your test
case.

Martin,
I'm rather shocked at your response!
Consider for example, there's a very popular tool out their that
integrates very well into NetBeans IDE and Eclipse IDE which suggests
changing all 'new Integer(), new Long()' calls into 'Integer.valueOf() &
Long.valueOf()'. Take a quick look at
wrt the Integer & Long values you use in your test case ...
You might consider using larger Integer & Long values, ones that lie
outside the range of Integer.IntegerCache & Long.LongCache to avoid any
potential confusion about whether the values you are putting into the
Map might get grabbed f
wrt ts-6434, the abstract just talked about performance case studies.
We didn't
know what the cases would be when we filed the abstract.

Charlie,
Test case code is different from regular code
in that bad practice is often a good idea.
People should know better than to "fix" test cases
using their IDE.
But I added this comment:

Charlie,
Hotspot engineers throughout the ages
have been tempted to optimize away
object identity semantics of Integer and String,
but I'm pretty sure that for e.g. new Integer(x)
and new String(y) hotspot will certainly continue
to return _new_ objects (unless of course

Peter, Thanks. Fixed.

I noticed a commit related to that a few weeks ago[1
