[Azure][Application Insights agent for Java]java.lang.NoClassDefFoundError: http/RequestLine

Question

After launch my jetty with applicationinsights-agent-1.0.6.jar as agent (See https://github.com/Azure/azure-content/blob/master/articles/application-insights/app-insights-java-agent.md ), I get following stack trace. Remove the agent remove the stack trace.

I don't understand why it bother with "java.lang.NoClassDefFoundError: http/RequestLine", I found this class nowhere ...

Is someone has the same issue?

According to the exception java.lang.NoClassDefFoundError , it means some dependent libraries like httpclient were missed in the command line.

As to resolve it, you need to download the zip file of Application Insights SDK for Java from the page , and append them with the : delimiter to the tail of the option -cp .

Any concern, please feel free to let me know.
