Greetings to the Java community. I have a question regarding the design of
java,time package.
Commercial Java developers deal with time periods all the time with
different validations regarding intersection of periods, big data
processing, entity auditing etc etc. And it is surprising for everyone

Sorry to send as follow up, those "to summarize" sentence is a question,
not a statement. Sorry for possible confusion

I have created some drafts of the EnumeratedStream API. But firstly, I have
noticed that we have not formalized problems we are solving with them.
Moreover, during the implementation process, I have discovered that there
are possibly a much wider range of applications for those streams. Instead

Has it been considered to add a readKey() method to IO class? In my
experience, it is pretty commonly used by beginners when they write things
like console games (snake, catcher game etc.). I am aware there is
System.in.read() method, but since we decided to promote some methods to
separate methods
Is it possible to make stable values and collections Serializable? I see
various applications for this feature in entity classes as a way to
preserve immutability of entity fields and at the same time not break
current JPA specifications. It is a *very* common task in commercial
development. Curren
Hi David. I am not a core libs team but I guess I can have some clues :).
It is hard to tell without the code, but I assume that there are a few
layers to it.
1. Stalling. I would assume it is caused mostly by GC pauses taking too
long (forever) if GC does not have any computational powers to run
as addressed this same problem; their approach worth reviewing:

Thanks. I will look into it for references. To my shame, I haven't looked
into guava when designing the API, so this will be really useful.

shape pretty heavily on the date time libraries.
Nevertheless, as you might see, API is type-agnostic, and one of the goals
is to make ranges specializable for different types (although this would
require additional research)

Is in-built gatherers list finalized? I was thinking that
Gatherers::uniqueBy(Function) could be very popular
among stream users, although it is fairly easy to implement yourself (as
well as bunch of currently in-built ones though)

Would appreciate any feedback.

Hello there. I am writing to address the overlap between class file
transformation using the ClassFile API and the work done by code-generating
annotation processors, and whether they ultimately solve the same problem.
Annotations such as @Async and @Transactional in popular frameworks are

Sorry for followup letter, just mentioned that I wrote that annotations CAN
change the semantics, while I meant CANNOT. With this typo letter makes
little to none sense, so correction is important

Hi. There has been a proposal from me (that Chen mentioned), approximately
