16:21 hhh joined #virtualJUG
16:22 dummkopf reflection issues with JDK 9?
16:22 dummkopf module not exposed probably
16:22 sjmaple this is just access problems rather than reflection
16:22 dummkopf yup.. that's right
16:23 sjmaple although reflection has another solution :)
16:23 dummkopf Base64.Encoder
16:24 mani1 Hurray! builds!
16:24 sjmaple hahah, bytebuddy... reflect all the things! :)

16:27 dummkopf Maven absolutely sucks! :D
16:27 dummkopf Gradle is so much better... comparatively speaking
16:27 mani1 sjmaple: question for Nikolas - would it be a good idea to preserve the ${argLine} property and append to it?
16:27 christopwner so much for mockito tests D:
16:28 null1 joined #virtualJUG
16:29 sjmaple Gradle doesn't support modules yet tho :(
16:29 nicjj joined #virtualJUG
16:29 sjmaple *sad-panda*
16:29 dummkopf sjmaple: :(
16:29 dummkopf I hope they bring it out before the official release!
16:30 sjmaple yeh, Java 9 classpath on gradle works just fine afaik
16:32 IvanKrylov joined #virtualJUG
16:33 mani1 sjmaple: can we run jdeps on this build app to see what it says?
16:39 mani1 Gradle is still working on its j9 issues - checkout their git repo
16:44 LAFK_pl it cannot see package annotation, not package xml-bind
16:46 Mikelevin joined #virtualJUG
16:51 LAFK_pl joined #virtualJUG
16:52 mani1 sjmaple: question for Nikolas - why are we not using the --module-path param, but -cp - is it due to presence of unnamed modules / jars?
16:53 sjmaple we're not modularising the app yet
16:53 mani1 aah! I see just compiling and running it
16:53 ganesh joined #virtualJUG
16:53 sjmaple so far it's just putting a J8 app onto the J9 cp
16:53 sjmaple yeo
16:53 sjmaple yep
16:54 sjmaple and it's Nicolai, btw ;)
16:55 Loord joined #virtualJUG
16:58 sjmaple any final questions for Nicolai?
16:58 mikec Are you going to post the link to this presentation?
16:59 sjmaple to the video or slides?
16:59 mikec either/both
16:59 sjmaple slides: http://slides.codefx.org/java-9-migration
16:59 Itachi joined #virtualJUG
16:59 sjmaple video will be the same youtube url
16:59 mikec ok thanks
16:59 sjmaple http://youtu.be/NKY2FYTCo7I
16:59 sjmaple np
16:59 mani1 sjmaple: how long is this session going to be? another hour?
17:00 sjmaple not sure :)
17:01 sjmaple I expect another 15-20 mins at most

17:05 Guest53126 joined #virtualJUG
17:15 Itachi joined #virtualJUG
17:15 Mikelevin joined #virtualJUG
17:15 mikec what I just took from all of that is that modules are not on the cp, and as we convert to modules --cp leaves and -addmodules is used, is that correct?
17:17 mikec ok, so modules can stay on the cp, Then why use a module path, what is the benefit?
17:17 sjmaple you would use -mp instead of -cp
17:17 mikec ok got it
17:17 sjmaple -addmodules is only used if your app does not depend on a module that you require to be loaded
17:17 dummkopf joined #virtualJUG
17:17 bobgutierrez joined #virtualJUG
17:18 sjmaple imo, modules is really only useful for library authors
17:18 sjmaple as the encapsulation can be useful
17:18 sjmaple if you wanted a modular codebase, you could use the module system to enforce that
17:18 sjmaple but imo, OSGi is better as it's more dynamic
17:19 mikec I was going to say that
17:19 sjmaple the only problem is, OSGi isn't part of base Java :)
17:19 sjmaple which is a PITA
17:19 bobgutierrez Is there  a github space for the shown code ?
17:20 sjmaple yep... https://github.com/CodeFX-org/demo-java-9-migration
17:20 mikec thanks gotta go
17:20 bobgutierrez Thanks
