Jetty ClassNotFoundException on Jetty 9.2.10.v20150310

See original GitHub issue

I am running a custom build of specialagent. I tried using the rule ‘specialagent-web-servlet-filter’, by setting the Jetty version to the one I needed, but keeping everything else unchanged. When I do so, I seem to get some strange classloading issues.

One that I can’t overcome yet is this ClassNotFoundException:

Any ideas of what is causing this? I realize that it is likely a Jetty version mismatch, since these rules targeted a later version, but any ideas would be helpful of where to start.

Looks like we are good to go. We aren’t seeing any issues so far. Awesome job! When do you think this might see a stable release?

Alright. Thanks for the analysis. Please let me know if there is anything I can do to help further debug or to try out custom instrumented builds.
