Subject [jira] [Commented] (KARAF-5384) Optional dependencies in MINA SSHD Core cause system bundle refreshes
Date Tue, 10 Oct 2017 11:52:00 GMT

    [ https://issues.apache.org/jira/browse/KARAF-5384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16198550#comment-16198550

Guillaume Nodet commented on KARAF-5384:

Well, there are some ways to improve the current situation:
  * use jline smaller bundles instead of the jline uber-bundle (this will remove the link
from mina -> ssh -> jline -> shell -> all commands)
  * we could repackage ssh to isolate it more and remove the import on mina (it's not really
needed as it defaults to using built-in nio2 anyway)

>                 Key: KARAF-5384
>                 URL: https://issues.apache.org/jira/browse/KARAF-5384
>             Project: Karaf
>          Issue Type: Bug
>          Components: karaf-core
>    Affects Versions: 4.1.0, 4.1.1, 4.1.2
>         Environment: Fedora Linux
>            Reporter: Seth Leger
>            Assignee: Jean-Baptiste Onofré
>            Priority: Critical
>             Fix For: 4.1.4
> In similar fashion to KARAF-5251, if you install any feature in Karaf that includes:
> - Apache MINA
> - bouncycastle
> - net.i2p.crypto
> it will cause the MINA SSHD Core bundle to refresh, which in turn refreshes most of the
core framework bundles. This has a variety of bad effects including:
> - Terminating the current SSH session
> - Terminating subsequent feature installations
> This is more severe than KARAF-5251 because these libraries are not part of the core
Karaf distro so it is not possible to add them to {{startup.properties}} without first repackaging
Karaf to contain the desired bundles in the {{/system}} directory.
> This also makes testing any Karaf feature that contains MINA, bouncycastle, or net.i2p.crypto
impossible in Pax Exam (unless you use org.apache.karaf.features.FeaturesService.Option.NoAutoRefreshBundles
or feature:install -r) because the refresh invalidates @Inject references in your test as
the core bundles are refreshed.
