19:02 blue61 OK, here is mine: With Java8 there has been an intelligent deducing of types for lambdas introduced into the compiler. Is there any other use for it apart from defining lambdas? Can it be used generally?

19:13 lalwanis Java 8 new feature functional programming is great but noticed the chaining with new functions can be confusing. Will Java 9 make that easier
19:13 OF joined #virtualJUG
19:14 TheShade Related: how easy it is to get the patch into Linux Kernel :)
19:15 HarmeetSingh joined #virtualJUG
19:16 TheShade No, we in OpenJDK do not do experience exams before accepting a patch.
19:16 TheShade But you need to sign a Contributor Agreement
19:16 blue61 Another Java8 related: when will JavaEE be in alignment with functional style? Will it ever be, considering Entity Beans are not immutable, and finders don't return streams? Will these features be at least partly done sometime?
19:16 geoL joined #virtualJUG
19:16 Guest48791 Why does the Optional implementation choose to assign  a special role to null values?  Causes trouble in many places.    Same with Stream.of(null).
19:17 jttkim so is there no code review by some independent pair(s) of eyes?
19:17 smarks there is definitely code review
19:17 domdorn joined #virtualJUG
19:17 Vivek_Krishnan joined #virtualJUG
19:17 EBGBs joined #virtualJUG
19:17 smarks there's no "entrance exam" but your code has to be reviewed and you have to establish a reputation
19:17 TheShade Code reviews are public. And non-Oracle engineers are routinely review code
19:17 Showtime When would you choose Java 8 and when would you choose Scala, and why?
19:17 arbb1 joined #virtualJUG
19:18 sjmaple you do need to pass an exam to understand the Contributor Agreement though ;o)
19:18 wesreisz For Simon, what is Jigsaw going to mean for how we write our apps?
19:18 katberg joined #virtualJUG
19:18 ShaunHubbard For Simon, the contributor agreement isn't that bad is it?
19:19 lalwanis yes Streaming I am talking about
19:20 real_zakaria joined #virtualJUG
19:20 TheShade Mr. Deprecators' remarks are not deprecating enough!
19:21 smarks That's >>Dr<< Deprecator to you, buddy!
19:21 real_zakaria do you need a phd to be able to contribute to projects like OpenJDK?
19:21 sievemaker Typesafe has changed own name to lightbend, is oracle planning the rebranding as well  to promote java9;) ?
19:22 sievemaker seriously...
19:22 sievemaker I think confusing is this...
19:22 sievemaker 'Optional is intended to provide a limited mechanism for library method return types where there is a clear need to represent "no result," and where using null for that is overwhelmingly likely to cause errors.'
19:23 nabilov joined #virtualJUG
19:23 nabilov hi all
19:23 sievemaker this is the quote from Brian Goetz
19:23 sievemaker 'where using null for that is overwhelmingly'
19:24 sievemaker i love this phrase
19:24 sievemaker ;)
19:24 hsk3mis And why Optional is not Serializable in Java8 ?
19:24 domdorn When can we use Optional in POJOs (right now, they are not serializable, even when the box value is serializable)
19:24 domdorn ha, my thought hsk3mis!
19:25 domdorn And when will the collection-apis also have methods for Optionals ?
19:25 firefoxNX joined #virtualJUG
19:25 embarros joined #virtualJUG
19:26 mselender joined #virtualJUG
19:27 mkalkov Will Project Jigsaw (modularization of Java 9) replace or complement OSGi?
19:28 sievemaker haha quesiton.... would be semicolons as an EOL sign removed one day from java.
19:28 TheShade semicolons are not EOL signs
19:29 blue61 Another Q: considering the update rate of the language infrastructure (not even JAF supports fluid programming upto now), when will the most important libraries support functional style? (i just recently had to change bean setter back to non-fluid style because JAF forced me to.)
19:30 neer joined #virtualJUG
19:30 sievemaker EOfStatement ;)
19:30 sievemaker but really we dont need them
19:31 mkalkov As for semicolons... I wish one day source code will be saved as AST, and formatted upon opening by my IDE. So we kill those formatting wars once and forever. :-)
19:31 sievemaker :)
19:32 hsk3mis And you'll need another standard for AST to agree upon ;)
19:32 nabilov @mkalkov i think Jigsaw modularization is just the same cof OSGI that will be integrated in OpenJDK
19:33 sievemaker but i think jshell is a cool thing!
19:33 DonRoberto joined #virtualJUG
19:33 sterpico joined #virtualJUG
19:34 pm771 I'm curious, what was the drive behind JShell?  What kind of urgent need does it fill?
19:34 kedarm Hasn't Java SE 7 been EOL'ed?
19:35 hsk3mis Ease of learning for new people, and to play new features for the experienced one... And every other language has it ;)
19:36 pm771 @hsk3mis - I believe "play" is a keyword in your answer.
19:36 hsk3mis probably
19:37 jttkim backwards compatibility can be a valid criterion but  it's sometimes taken too far ... see my generics question in the forum...
19:37 sievemaker i am still curious about pattern matching in java
19:37 sievemaker what do you think about javaslang project
19:38 The joined #virtualJUG
19:38 nickolay joined #virtualJUG
19:40 Jaymoid joined #virtualJUG
19:41 blue61 Another Q: in the project i work on there are a large number (about 250) Swing JPanels in use. We may need to migrate them to JavaFX, if i understand the deprecation of swing correctly. Will there be any supporting tools to migrate swing panels to JavaFX? Maybe a generator to read Layoutmanager data and output JFX layout data?
19:41 sievemaker would be sth like extern public ;) ?
19:41 sievemaker really public
19:41 sievemaker get rid of swing and javafx ;)
19:43 nickolay left #virtualJUG
19:45 Guest81925 How about type aliases?  Any plans for them in the future?
19:45 sievemaker yeah type aliases would be a great thing!
19:50 furetto joined #virtualJUG
19:50 Guest81925 What's going to happen with value types in terms of equals() and hashCode() and how will you make user-defined value types work in hash-based collections?
19:50 jttkim I don't agree that the use cases that would benefit from proper generics are "corner cases" -- this is just an indication that the community has adapted to the shortcoming in the last 10 years.
19:52 Mkonda joined #virtualJUG
19:52 mkalkov Indeed, Eclipse had a Java REPL since loooong ago, but it is called Java Scrapbook.
19:54 merikan joined #virtualJUG
19:55 merikan left #virtualJUG
19:57 rezwhap Honestly I don't even know why we are talking about the need for a REPL. I can't imagine anyone that has used one not thinking they are a great idea.
19:58 sievemaker yes repl is great but talking about it is boring
19:58 avalanche joined #virtualJUG
19:59 wesreisz Thank you for doing this roundtable.
20:00 sievemaker im not sure
20:00 sievemaker if is a good explanation ;)
20:00 sievemaker 'you can use it if you want' :D
20:00 sievemaker and nothing will stop you :D
20:00 sievemaker :D
20:01 avalanche is there any intention of adding worksheets (like scala worksheets as an alternative to the REPL)?
20:01 rezwhap was the collection optional question about things like Map.get returning null?
20:03 Jaymoid No, rezwhap, it was about collections returning  an Optional
20:03 mkalkov JavaFX still requires GTK2 on linux, and there are no plans to migrate it to GTK3 yet, so...
20:03 atas joined #virtualJUG
20:04 Jaymoid instead of null
20:05 Guest96531 More specifically, Scala / Spray Rest API vs. Java 8 / Spring Rest API
20:05 karstensrage i get along without a REPL
20:06 karstensrage ideone is pretty good if you need one
20:06 blue61 Great to hear Swing will not be deprecated any soon... hope the support of Swing will recover then ;)
20:06 Jaymoid Surely Generics was bigger
20:06 karstensrage and once you get past small toys, REPL's are useless
20:07 Mkonda Is oracle committed to Java?!
20:08 Showtime Semicolons rock!
20:08 rezwhap Haha yes more semicolons in English too!
20:08 Jaymoid How many years has it been under Oracle?
20:08 Vivek_Krishnan agree to disagree
20:08 Guest81925 Semicolons are great; they separate clauses.
20:08 Jaymoid do we need to ask that question now?
20:08 jttkim trying to get rid of semicolons will make Java a sorry clone of the mess that is R... ;-)
20:08 blue61 great session, thank you all :)
20:08 neer It was fun :-)  Thnx
20:08 kedarm Thanks everyone!
20:08 Jaymoid their backing of open jdk alone shows support
20:08 Vivek_Krishnan Java 5 was definitely a good change
20:08 pm771 thx
