I might need to change the title to refer to pax logging.
Phenomenon observed:
log entry
... 2 more
Desired outcome:
log entry
log entry
log entry
Notice that the entries in the desired outcome have not been curtailed.
Background
When using Apache Karaf, which uses the log4j 2 interface, there is a properties file
etc/org.ops4j.pax.logging.cfg where I can setup what gets logged and how. How do stop it from curtailing log entries as shown above?
org.ops4j.pax.logging.cfg

Steps to reproduce
Install Karaf 4.2.4
Make new Java project
mvn archetype:generate \
-DinteractiveMode=false \
-DarchetypeGroupId=org.apache.maven.archetypes \
-DgroupId=com.testproject \
-DartifactId=karaftest
Add a dependency that Karaf is unaware of. Do not add a features.xml. I used a pom.xml to make this easier.
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-blueprint</artifactId>
<version>2.22.2</version>
<scope>provided</scope>
</dependency>
Main.class:
import org.apache.camel.blueprint.BlueprintCamelContext;
/**
* Hello world!
*
*/
public class App
{
public static void main( String[] args )
{
BlueprintCamelContext blueprintCamelContext = new BlueprintCamelContext();
System.out.println( "Hello World!" );
}
}
Make a bundle. I maven's pom.xml and swapped out the packaging value and added the maven-bundle-plugin to the build command.
<packaging>bundle</packaging>
<build>
<plugins>
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<version>2.4.0</version>
</plugin>
</plugins>
</build>
Build it
mvn clean install
Place bundle's jar into Karaf's deploy folder.
Karaf will not start the bundle. Start the bundle start 45 (Default bundle id on a fresh install will probably be 45.)
Run log:set debug and log:display. Look for an OSGI osgi.wiring.package error, because I did import the dependency in the MANIFEST.MF (add in the pom.xml)
