Subject [jira] [Commented] (KARAF-5356) feature:install fails if log4j has a fragment attached
Date Fri, 08 Sep 2017 16:48:00 GMT

    [ https://issues.apache.org/jira/browse/KARAF-5356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16158904#comment-16158904

Johannes Utzig commented on KARAF-5356:

A workaround for the issue seems to be adding the log4j2 bundle into the same feature:

<feature name="base-startup" version="${project.version}" install="auto" hidden="true"> 
    <bundle start-level="7">mvn:org.example/myfragment/${project.version}</bundle>
    <bundle start-level="8">mvn:org.ops4j.pax.logging/pax-logging-log4j2/1.10.1</bundle>

>    Affects Versions: 4.1.2
>            Reporter: Johannes Utzig
> I am facing an issue similar to KARAF-4129
> To add a custom appender, I created a fragment for pax-logging-log4j2.
> We create a custom distribution with this fragment. To make sure the fragment is attached
to log4j2, I created a feature for it and added it to the startupFeatures
> {code:xml}    <feature name="base-startup" version="${project.version}" install="auto"
>         <bundle start-level="7">mvn:org.example/myfragment/${project.version}</bundle>
>                     <startupFeatures>
>                         <feature>base-startup</feature>
>                         <feature>framework</feature>
>                     </startupFeatures>{code}
> When starting this custom distribution, it works fine initially, but when you try to
install a new feature (like webconsole for instance) you end up with:
