Seth Leger commented on KARAF-5384:
-----------------------------------
My concern is that MINA is a very popular dependency and that many Karaf users
may try to install features that use it. The failure mode for this is *very*
difficult to diagnose for a casual Karaf user. It's very unexpected to see your
SSH session disconnect or core bundles restart or Pax Exam stop working just
because you included MINA in a feature definition.
I would recommend that the Karaf project takes a proactive approach to problems
like this by repackaging core bundles with rewritten manifests that do not have
optional dependencies, or rewrite the core features so that all optional
dependencies are installed for the core bundles.

> 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
> Priority: Critical
> Fix For: 4.1.3
>
>
> 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.
