Subject [jira] [Commented] (KARAF-3888) Karaf refreshes a lot of unrelated bundles during feature installation
Date Mon, 03 Aug 2015 09:59:04 GMT

    [ https://issues.apache.org/jira/browse/KARAF-3888?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14651693#comment-14651693
] 

Christian Schneider commented on KARAF-3888:
--------------------------------------------

The jline problem is actually fixed. We just use the wrong activemq snapshot. It should be

feature:repo-add mvn:org.apache.activemq/activemq-karaf/5.11.2-SNAPSHOT/xml/features

With this version I do not get the shell refresh when installing camel, I still get it when
installing cxf though. 
When digging into it I found that jline is now wired to camel-core:
jline/2.12.1 (Wired to org.apache.camel.camel-core/2.15.2 which is being refreshed)
This should also not be the case and points to a bug in camel-core. 

When installing cxf camel-core is refreshed because it has an optional dependency on xalan
which cxf brings. So the refresh of camel-core is normal but not the refresh of jline.

The issues with the many refreshes when installing feature:install -v -t cxf-ws-policy is
still there.
org.apache.activemq.activemq-osgi/5.11.2.SNAPSHOT (Wired to org.apache.aries.transaction.manager/1.0.0
which is being refreshed)
    org.apache.aries.transaction.manager/1.0.0 (Should be wired to: org.apache.geronimo.specs.geronimo-jta_1.1_spec/1.1.1
(through [org.apache.aries.transaction.manager/1.0.0] osgi.wiring.package; filter:="(&(osgi.wiring.package=javax.transaction)(version>=1.1.0)(!(version>=2.0.0)))"))
The cause here is a rebinding of transaction manager.

>          Components: karaf-feature

> To reproduce the problem:
> {noformat}
> feature:repo-add mvn:org.apache.cxf.karaf/apache-cxf/3.1.1/xml/features
> feature:repo-add mvn:org.apache.camel.karaf/apache-camel/2.15.2/xml/features
> feature:repo-add mvn:org.apache.activemq/activemq-karaf/5.11-SNAPSHOT/xml/features
> feature:install activemq
> feature:install activemq-client
> feature:install camel
> feature:install cxf
> feature:install -v -t cxf-ws-policy
> {noformat}
> The result of the last command is in file [^karaf-refresh-problem] which is attached
to this bug. In short:
> {noformat}
> karaf@root()> feature:install -v -t cxf-ws-policy
> Adding features: cxf-ws-policy/[3.1.1,3.1.1]
> No deployment change.
>   Bundles to refresh:
>     activemq-karaf/5.11.0.SNAPSHOT (Wired to org.apache.activemq.activemq-osgi/5.11.0.SNAPSHOT
which is being refreshed)
>     javax.mail/1.4.4 (Wired to org.apache.activemq.activemq-osgi/5.11.0.SNAPSHOT which
is being refreshed)
>     jline/2.12.1 (Wired to org.apache.activemq.activemq-osgi/5.11.0.SNAPSHOT which is
being refreshed)
>     net.sf.ehcache/2.9.0 (Wired to org.apache.aries.transaction.manager/1.0.0 which is
being refreshed)
>     (about 90 other bundles)
> karaf@root()>
> {noformat}
> In the same time, if I slightly change the order of feature installation (install activemq-client
_before_ activemq), then the refresh doesn't happen:
> {noformat}
> karaf@root()> feature:install -v -t cxf-ws-policy
> Adding features: cxf-ws-policy/[3.1.1,3.1.1]
> No deployment change.
> karaf@root()> 
> {noformat}
> Note regarding AMQ vesrion - I'm using 5.11-SNAPSHOT because of a fix for another bundle
refresh problem: https://issues.apache.org/jira/browse/AMQ-5821
