Summary: Concurrency issues in FeaturesService related to
add/remove/list operations
Key: KARAF-3017
URL: https://issues.apache.org/jira/browse/KARAF-3017
Project: Karaf
Issue Type: Bug
Affects Versions: 2.3.5, 3.0.1
Reporter: Grzegorz Grzybek
I have concurrent scripts (using shell {{bin/client.sh}} commands) which invoke
{{features:listurl}}, {{features:addurl}} and {{features:removeurl}}.
Sometimes I get {{NullPointerException}} here:
{code:java}
public Repository[] listRepositories() {
Collection<Repository> repos = repositories.values();
return repos.toArray(new Repository[repos.size()]);
}
{code}
when
{{org.apache.karaf.features.internal.FeaturesServiceImpl#removeRepository(java.net.URI)}}
is invoked between {{repos.size()}} and {{repos.toArray()}}.
