10:03 rene-enriquez- and how to do that
10:03 blalasaadri You can set the video quality on Youtube. That makes it much less blurry. ;-)
10:03 rene-enriquez- it's not working
10:03 Eddy joined #virtualJUG
10:03 cdthompso1 for blur, mouseover the youtube window, click sprocket icon in lower right, and change "quality"
10:04 ishan joined #virtualJUG

10:09 rene-enriquez- thanks
10:09 TheKingJasper Will they all break?
10:10 blalasaadri Now audio and video are gone. :-(
10:10 kirant Backward Compatibility??
10:10 HarmeetSingh no audio
10:10 kirant no audio and video?
10:11 zarkopafilis On packaging, why org.astro is package with version 1.0 but the module with the main class, not packaged with a version?
10:12 TheKingJasper So will there be Backward Compatibility??
10:12 Sumit I am trying 01_greetings

10:18 HarmeetSingh no clear, yet
10:18 JoseMiguel22 sound is back
10:19 sjmaple unless people think it would be useful to see someone's screen and watch them work through particular exercises?
10:19 JK joined #virtualJUG
10:19 sjmaple If people want that, we can do that too
10:19 HarmeetSingh @sjmaple still, I am confuse with agenda
10:19 codefire joined #virtualJUG
10:20 codefire its not clear at all
10:20 blalasaadri1 It would be useful to see the exact code someone is looking at while explaining it. Whether that's via audio or IRC is a secondary issue.
10:21 zarkopafilis ServiceLoader ROCKS!!
10:21 felipeps_souza joined #virtualJUG
10:21 zarkopafilis Now I'm thinking what's spring gonna do with this whole ecosystem around DI
10:22 elendis joined #virtualJUG
10:22 HarmeetSingh Yep, it is clear
10:22 karianna Trying to answer some questions here:
10:23 karianna The Java 9 code samples willalmost certainly not run in an IDE as IDE support is not uptodate yet
10:23 HarmeetSingh Okay, Thanks @sjmaple
10:23 TheKingJasper So will there be Backward Compatibility?
10:23 karianna @TheKingJasper - sort of
10:23 rene-enriquez- cool
10:23 zarkopafilis TheKingJasper na
10:23 zarkopafilis betterwrite java 8
10:23 karianna To answer Backwards compatibility
10:23 karianna To answer Backwards compatibility:
10:23 TheKingJasper Rip.
10:23 zarkopafilis compiling 9 to work backwards is not a good idea
10:23 MarczykM may be useful for someone http://www.webupd8.org/2015/02/install-oracle-java-9-in-ubuntu-linux.html
10:24 gummi_icejug joined #virtualJUG
10:24 zarkopafilis I think it's the first time they removed some methods breaking compatibility as well
10:24 hendrik_ebbers joined #virtualJUG
10:24 karianna Running Java 6,7,8 code in Java 9 will work but if you rely on any sun.misc.Unsafe or other 'internal' modules then you'll need to use special flags
10:24 viktar joined #virtualJUG
10:24 rene-enriquez- scripts are working so good, but just for the sake of simplicity, is currently any IDE that supports this compilateion?
10:25 JavaGhost_ joined #virtualJUG
10:25 QR joined #virtualJUG
10:25 karianna If you compile Java 9 code in a *modular* manner then that will *not* run on older versions of Java
10:25 javapapo this channel is not very helpful towards coordinating the event especially locally
10:25 hendrik_ebbers I*m using IntelliJ 2017 preview for Java9
10:25 kirant i am using Intellij
10:25 javapapo I guess a temp slack channel would much better
10:25 karianna If you compile Java 9 code in *classpath mode* then that might work
10:25 zarkopafilis Everything, IntelliJ has got some experimantal j9 support integrated for half an year now
10:25 dove_ joined #virtualJUG
10:25 Javilete Using Intellij here as well
10:25 javapapo IntelliJ +1
10:25 rene-enriquez- nice advice guys
10:25 zarkopafilis yeah but *classpath mode* should be left behind
10:26 kirant Intellij works OK with Java 9
10:26 zarkopafilis It's not like you are required to use j9 to talk to some random legacy program
10:26 amczarny joined #virtualJUG
10:26 hendrik_ebbers For my JShell Samples later I will use IntelliJ 2017 Community edition, too. Would make sense if you have installed it. WIll makes thinks easier ;)
10:26 zarkopafilis ULTIMATE will do I guess
10:27 HarmeetSingh while running first example, compile.sh script, I am getting this error compile.sh: 15: compile.sh: OSTYPE: parameter not set
10:27 karianna @zarkopafilis - but if your Java 9 program (modular version) wants to include 3rd party libs there can be issues
10:27 sanjeev joined #virtualJUG
10:27 karianna There's still a bit of discussion on how this will work easily (auto-modules)
10:27 sjmaple @HarmeetSingh wanna join the hangout and screenshare?
10:28 HarmeetSingh okay, sure
10:28 sjmaple we can work though together maybe, I'll DM you the link
10:28 zarkopafilis @karianna yeah that's the point, you gotta wait for everyone to update unless you use some external framework to pass them around and make them accessible via a ServiceLoader or something like that
10:28 pcllau joined #virtualJUG

10:28 hendrik_ebbers @sjmaple should we give a short introduction how to use J9 in IntelliJ Community edition?
10:29 pliakas joined #virtualJUG
10:29 zarkopafilis Look at what .net is doing, rewriting whole framework with parts of language ,destructive changes if you want it to run on linux and they dont even care
10:29 Teyo +1 short intro, J9 on IntelliJ
10:30 rene-enriquez- yeah, Alberto Salazar from Ecuador is there

10:30 kirant yes
10:30 kirant its working with intellij
10:30 zarkopafilis javapapo kalhmera :3
10:31 javapapo Intellij -> Open -> Pick the 'Greetingsxxx' folder it should automatically pick it up
10:31 javapapo 2017.1 supports module-info
10:31 michael_bateman get this java.lang.module.ResolutionException: Modules deploy and plugin.legacy export package com.sun.deploy.uitoolkit.ui to module javafx.swt
10:31 Jitendra intelliJ 2017
10:34 Teyo (y) thanks
10:34 rene-enriquez- I'm currently working on 05_Missing_exports. Just wondering, it means that we have to export every single package from a module?
10:35 spatial Choose VCS and git clone in 2017 IntelliJ directly
10:35 zarkopafilis rene-enriquez- only whatever is used by your program or you wish to make available as a library

10:56 zarkopafilis Not exactly, just to showcase how you can compile without caring about dependencies
10:57 zarkopafilis They only get evaluated on runtime after all
10:57 zarkopafilis keep going and you will understand it

11:00 JoseMiguel22 another issue in scripts to run and compile. $COM_GREETINGS_FOLDER is a variable in build, but is hardcoded in run
11:00 kennedy_sigauke Does the order of the dependencies determine how each module is compiled? If that's the case, how does Java 9 deal with circular dependencies where modules can be dependent on each other?

12:28 mani2 @ishan you use the Java command to run things, have a look at the script - if its created using the --launcher option, the exeutable is inside the distributable folder, otherwise you say   <folder>java/bin/ ... (its iin the jlink exercise)
12:28 Youri joined #virtualJUG
12:29 mani2 @harmeet: there is an exercise on JMod, and some info in the README, with links to resources, at the moment the use of JMod is limited, its used to create module packages (bundle one or more modules or packages into a single file)
12:30 stfs-vjug (I added this to the GDoc file as well): I noticed that the executable directory that is generated in session 01 is only 44 Mb. Is the build process limiting the JDK modules that it includes somehow? If so, how? There doesn’t seem to be any info about what JDK modules to include in the module-info.java files in the project.
12:30 HarmeetSingh @mani2 is it possible to run jmod file like jar ?
12:31 mani2 HarmeetSingh: its similar to running JImage but not like jar - the command does not produce jar compatible (binary compatible) files.
12:31 HarmeetSingh I am sorry, But i am not familiar with jimage ?
12:32 blalasaadri1 The JMod example seems to be missing the com.greetings sources. Copying them from the JLink example works though.

12:33 mani2 blalasaadri: thanks again mate
12:33 HarmeetSingh @mani2 i was going though this readme, but still, its bit confusing, what is jimage ?
12:33 mani2 HarmeetSingh: no you can run JMod files - just now its not clear what the use it, so far we know we use it to encapsulate modules + jar (fatjar like)
