An honest question,
why do we need so many interfaces for the different categories of
RandomGenerator ?
My fear is that we are encoding the state of our knowledge of the different
kinds of random generators now so it will not be pretty in the future when new
categories of random generator are

Hi Patrick,
I still don't like the fact that IntMapMultiConsumer, DoubleMapMultiConsumer
and LongMapMultiConsumer are not in java.util.function unlike all other
functional interfaces used by the Stream API.
Otherwise looks good.

Hi Patrick & Julia,
this version starts to look good.
I just don't understand why the new functional interfaces are not in
java.util.function like the other ones ?
(BTW, in the javadoc, the link to the summary overview point to the wrong one,
to java.util.stream and not java.util.function).

Hi Sergei,
the problem is that you are changing the semantics if there are several fields.
By example with the code below, you have the guarantee that the code will print
4 (if it prints something),
if you remove the assignment field = false, the code can print 0 or 4.
class A {
int i =

Hi Mndy,
Looks good,
I don't like too much the fact that there is a new boolean field in j.l.r.Field
instead of using the modifiers like in the VM counterpart,
but it will require masking and unmasking the modifiers which is a far bigger
change, too big to worth it in my opinion.
So +1

yep,
the inference is not smart enough.
So the way to fix the code is either to explicitly specify the type arguments
var rs1 = x.entrySet().stream().sorted(
Map.Entry.comparingByValue().reversed()
);
or to store the result of comparingByValue() in a variable (so it's a poly

Hi Claes,
For the code below the comment "Mock the recipe to reuse the concat generator
code",
i believe you can use String.repeat() that was introduced recently.
The code that parse the the receipe can be in its own method to make the code
more readable,
this method returns the list and use

Hi Claes,
so instead of having a prefix and a suffix, there is only a prefix, a suffix
being seen as a prefix for the next iteration
and if at the end instead of just allocating an array, you allocate an array
and stuff it with the last prefix.
Are you sure having a suffix at the end is

Hi Claes,
do you have evaluated the improvement (1) in separation of the others ?
(2) or (3) are clearly improvement but (1) is a trade of because you are adding
a second lookup into another table and make prepender() less likely to be
inlined.

Hallo !
This questions have been asked so many times since 1998,
Josh Bloch one of the designer of the API (who will later write Effective Java)
as created a FAQ around that time answering to that question:
https://docs.oracle.com/javase/8/docs/technotes/guides/collections/designfaq.html
Hi Mandy,
i've taken a look to the code,
i think it's better to have two methods, one for List and one for Map to avoid
to have a bootstrap argument ( classDataType ) and to have a code more
straightforward.

Hi Maurizio, Mandy,
In

using a condy inside a static init make me sad,
using a late loading constant to early load it in the static init seems
BTW, did you try to add an intermediary private non visible class between
Vector and IntVector to avoid all hand-written cast inside the implementation
of IntVector,
something along that line
public abstract class Vector {
abstract void foo(Vector vector);
abstract Vector bar();
}
Hi Paul,
about the API part (not the implementation),
there are location where the same concept is described with a different names
which doesn't help to understand how thing work

- vector shape <=> vector bits size
- element size <=> lane size

you can introduce a local variable for that.

Hi Claes,
looks good,
it can be written in a less Doug Lea-ish way like this
V v = get(key);
return (v != null)? v: default;
I believe it using the same number of bytecodes :)
with a ALOAD instead of a DUP

Hi Claes,
In ArchivedModuleGraph, there is no point to take the mainModule as parameter
given that it should always be null.
In ModuleLoaderMap, the constants PLATFORM_LOADER_INDEX and APP_LOADER_INDEX
should be moved inside the nested class Mapper given that there are only needed
by the
Stuart, Martin, Kiran,
I think this "bug" should not be fixed because it's one of the cases where
providing more information is actually bad from a user POV.
The current code throws NoSuchElementException when the iterator reach the end
so from the user POV, this is the right exception because

Hi Robert,
first this is the wrong mailing list,
this mailing list is about how to implement the JDK, not how it works,
usually stackoverflow is better for the kind of questions you are asking.

Seem to be a JIT bug to me,
the fields of Set12 are declared final not @Stable (even if the field storing
the instanceof of Set&2 itself is marked @Stable) so there is no reason not not
let the constant folding happen.

Hi Roman,
addAll() returns a boolean that will be not easy to compute given that
forEach() takes a lambda (that can only capture local values and not change
them).
and the javadoc of AbstractCollection clearly states that addAll has to use an
iterator if implemented
Hi Maurizio,
that's a huge work :)
So as a guy discovering the API,
i've not taken a deep look to the implementation because i've noob questions.
The first sentence of the overview of GroupLayout should say that there are two
types of GroupLayout struct and union instead of talking about
Nice !
there is a wikipedia article about WAVL tree [1].
I did not know this new kind of balanced tree, worth the exploration i believe.
and TreeMap code really needs some love anyway, unlike ArrayList and HashMap,
this code has not be updated since a long time.

Hi Sergey,
hum, it doesn't work :)
int.class is compiled by javac as Integer.TYPE,
the opcode ldc only works with an object/interface class, not with a primitive
type [1].

There is perhaps a better way, as part of the branch nestmates of valhalla,
Mandy has added a way to transfer a live object to a Class when defining it,
with that you can send all the Methods as an array and in the bootstrap method
of a condy, access to the right method by extracting it from the array usi

Hi Jorn, Claes,
Is it not better to always store in a local variable, like javac does, instead
of doing the double SWAP if there is a return value of size 1 ?
