Description

I have observed following behavior: there is a feature containing a repository URL inside the feature.xml:

<?xml version="1.0" encoding="UTF-8"?>
<features 
        name="${project.artifactId}-${project.version}"
        xmlns="http://karaf.apache.org/xmlns/features/v1.0.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xsi:schemaLocation="http://karaf.apache.org/xmlns/features/v1.0.0 http://karaf.apache.org/xmlns/features/v1.0.0 ">

    <repository>mvn:org.mycompany/thirdparty-features/9.9.9/xml</repository>

    <feature name="test-bad" version="${project.version}">
        <feature>thirdparty-commons</feature>
    </feature>
</features>

The repository URL mvn:org.mycompany/thirdparty-features/9.9.9/xml is not exist and cannot be resolved.
I specify the feature URL in org.apache.karaf.features.cfg featuresRepositories, but NOT mention the feature in featuresBoot:

featuresRepositories = \
    mvn:org.apache.karaf.features/enterprise/4.0.1/xml/features, \
    mvn:org.apache.karaf.features/framework/4.0.1/xml/features, \
    mvn:org.apache.karaf.features/spring/4.0.1/xml/features, \
    mvn:org.apache.karaf.features/standard/4.0.1/xml/features,\
    mvn:org.mycompany/test-bad/1.0.0-SNAPSHOT/xml

#
# Comma separated list of features to install at startup
#
featuresBoot = \
    aries-blueprint, \
    bundle, \
    config, \
    deployer, \
    diagnostic, \
    feature, \
    instance, \
    jaas, \
    kar, \
    log, \
    management, \
    package, \
    service, \
    shell, \
    shell-compat, \
    ssh, \
    system, \
    wrap

Current behavior:
1) Karaf writes error message in the log file:
java.io.IOException: Error resolving artifact org.mycompany:thirdparty-features:xml:9.9.9: Could not find artifact org.mycompany:thirdparty-features:xml:9.9.9 in central (http://repo1.maven.org/maven2/) : mvn:org.mycompany/thirdparty-features/9.9.9/xml
(absolutely correct)
2) further startup process is completely blocked (problem)

Expected behavior: write error message and continue startup process: feature is not specified in featuresBoot and must not be installed.

Interesting, if unresolved feature URL is specified directly in featuresRepositories, Karaf proceed it correctly: writes error message, but continues startup. Blocking appears only if unresolved URL is specified inside the feature.xml.
