Achim Nierbeck commented on KARAF-2840:
---------------------------------------
thanks for the patch.
I'm always a bit confused where the difference is between a admin:create and
admin:clone.
That's why I thought that the clone command should do this. A create is
supposed to work as a unzip of the karaf.zip
Where this configuration isn't done either.
Or did I get this totally wrong? If so never mind my brabling ....
> Creating child container using admin service should use KARAF_OPTS
> ------------------------------------------------------------------

> Key: KARAF-2840
> URL: https://issues.apache.org/jira/browse/KARAF-2840
> Project: Karaf
> Issue Type: Bug
> Components: karaf-core
> Affects Versions: 2.3.4
> Reporter: Claus Ibsen
> Assignee: Guillaume Nodet
> Fix For: 2.3.5
>
> Attachments: karaf2840.patch

>
> When you use admin:create to create a child container, then the AdminService
> is used to create the JVM process. This code does not read the KARAF_OPTS
> environment variable which means the child container does not use that when
> started.
> But if you use the bin/start script to start the child container, then the
> setenv script will read the KARAF_OPTS.
> So that means there is a difference between using the admin commands to
> crate|start child containers, vs using the bin scripts.
> This is a serious problem for Windows users on IP6 network that hits a well
> known issue, where they have to set a JVM system property to work around this.
> If they do not you get network issues such as
> java.net.SocketException: Permission denied: no further information
> To fix this with Karaf you set this option
> KARAF_OPTS '-Djava.net.preferIPv4Stack=true'
> Maybe either globally in the Windows box, or in the bin/setenv.bat file.
> But the child containers do not pickup that env option when created by admin
> server.
> This patch fixes that.
> To see if the env option was picked up by Karaf, you can connect to the child
> container, and run
> {code}
> dev:system-property | grep java.net
> {code}
