> 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()}}.
