Peter Berkman created KARAF-5210:
------------------------------------
Summary: Seemingly random NPEs from Aether resolver
Key: KARAF-5210
URL: https://issues.apache.org/jira/browse/KARAF-5210
Project: Karaf
Issue Type: Bug
Affects Versions: 4.1.1
Environment: Windows
Reporter: Peter Berkman
We have an installer that automates much of our Karaf and product installation.
since the upgrade to Karaf 4.1, I've been getting these about every 5th
automated install. could be timing? Happens at random places and sometimes with
dependencies that the target doesn't have.
One thing is that we do turn OFF internet access for maven through settings in
the org.ops4j.pax.url.mvn.cfg and provider our out mvnsettings.xml. I will try
and attach them later, but these are the relevant settings:
<pre>
org.ops4j.pax.url.mvn.settings=${karaf.etc}/mvnsettings.xml
org.ops4j.pax.url.mvn.localRepository=${karaf.data}/repo
org.ops4j.pax.url.mvn.useFallbackRepositories=false
org.ops4j.pax.url.mvn.defaultRepositories=
org.ops4j.pax.url.mvn.defaultLocalRepoAsRemote=true
org.ops4j.pax.url.mvn.repositories= \
file:${karaf.home}/${karaf.default.repository}@id=system.repository@snapshots,\
file:${karaf.data}/kar@id=kar.repository@multi@snapshots
</pre>
Here is what the stack looks like - note that the target bundle is almost
always different on different failures.
