Jax RS Tracing broken

[chouze]

We upgraded our java agent to version 0.12.0 and noticed that we no longer received any traces for servlet.request in the Datadog APM dashboard. To the best of our knowledge we still received all the traces for all other types. We reverted back down to 0.11.0 and started receiving the servlet.request traces again. We are running jetty version 9.3.6.v20151106 and jersey version 2.22.1.

Thanks for the report. Would it be possible to open a support ticket so you can provide some logs and such?

[chouze]

Opened ticket #160129 for this issue.

@chouze We are waiting for a response on that ticket. Providing logs, specifically the jvm startup logs with -Ddatadog.slf4j.simpleLogger.defaultLogLevel=debug enabled would be especially helpful.

Thanks!

Hello, sorry for the delay, I've sent in a few minutes of logs.

@chouze We've made a fair bit of changes since 0.12.0. I was wondering if you'd be willing to try again. I don't have any particular reason to think we've fixed it, but I also don't know what is causing it, so I'm kinda hoping it's been unintentionally resolved. This is the particular log line that is problematic:

[main] DEBUG datadog.trace.agent.tooling.AgentInstaller$LoggingListener - Failed to handle javax.servlet.http.HttpServlet for transformation on classloader sun.misc.Launcher$AppClassLoader@18b4aac2: Cannot resolve type description for javax.servlet.ServletRequest

Thanks!

Hi @tylerbenson, I just tried with 0.15.0~71059eac It seems to be having the same issue as 0.12.0

[tylerbenson]

@choze, darn. I was hopeful. Is it possible for you to provide a small sample app that reproduces the problem?

Can you tell me more about your application environment? Using Spring Boot, OSGi, or some other non-standard classloading setup?

[ghost]

from my experience, servlet.request is reported for spring boot services, but jersey services use a different format which is based on the class name and method name of the API endpoint. Perhaps that is the point of confusion?

Closing as abandoned.

We've made significant improvements to the tracer in the past year (and specifically Jax-rs more recently)

Please open a new issue if the problem persists with a newer version of the tracer.
