Need help to use it in the apache karaf/service mix enviroments

Hi, would you share your command line running with the jvm profiler, and the full error stacktrace?

[vMuvvala459]

Hi Sorry for the late response. Below are the details.

1. installed service mix in debian
2. created simple bundle and deployed it in the apache service mix.
3. created jvm-profile jar by runining mvn clean package
4. copied jvm-profiler.jar to /home/apache-servicemix-7.0.1/lib/boot/ directory.
5. edited <service_mix_home_directory>/etc/config.properties.

org.osgi.framework.bootdelegation

org.apache.xml.serialize, \ ( existing/default last entry)
com.uber.profiling \ ( add this line at the end).

5. edit servicemix.sh file to include -javaagent

javagent="/home/apache-servicemix-7.0.1/lib/boot/jvm-profiler-1.0.0.jar=reporter=com.uber.profiling.reporters.ConsoleOutputReporter,tag=mytag,metricInterval=5000,
durationProfiling=com.learning.bundle.simplebundle.Activator.method1"

below is the stack trace.
