John Ellinwood commented on KARAF-1729:
---------------------------------------
I can reproduce the problem on karaf apache-karaf-3.0.2-20141010.122359-267. I
see this creep up in a number of situations from KAR installations with
incomplete feature installations, blueprint bundles in grace period, to simple
bundles that aren't finished starting. One of our test procedures involves
shutting the power off to our machine and seeing if things come back
successfully, and this issue regularly affects us.
I believe the root of the problem may be with bundles that have not fully
started when the karaf process is killed. I will attach a maven project
containing a simple bundle that can be used to reproduce the issue. Simply put
a Thread.sleep() loop in a bundle activator, kill the karaf process, restart
karaf, attempt to do anything to the bundle in question (e.g., uninstall,
headers, etc). I
To reproduce the problem:
start a clean karaf
karaf> install mvn:example/invalid-maven-bundle/1.0.0-SNAPSNOT
kill -9 <karaf pid>
start karaf agaiin
karaf> uninstall <invalid-maven-bundle id>
Bundle is invalid
No bundles specified.
The bundle activator looks like:
package example.karaf_invalid_bundle;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
public class Activator implements BundleActivator {
public void start(BundleContext context) {
System.out.println("Starting the bundle");
while(true) {
try {
Thread.sleep(10000);
} catch (Exception e) {
}
}
}
public void stop(BundleContext context) {
System.out.println("Stopping the bundle");
}
}
I will continue to investigate this by debugging karaf in the invalid state and
attempt to see where things went wrong, and hopefully I can then determine
where in startup this happens.
