IllegalAccessError - incompatible with New Relic

[PacoSwifty]

In the UserVoice init method we are seeing a chain of calls that ultimately gets to BabayagaTask.doInBackground(args) which is using OkHttp. It seems like it's using a version of OkHttp that is not compatible with NewRelic and is causing a crash.

E/UncaughtException: java.lang.RuntimeException: An error occurred while executing doInBackground() ......

Caused by: java.lang.IllegalAccessError: Method 'void com.squareup.okhttp.Call.(com.squareup.okhttp.OkHttpClient, com.squareup.okhttp.Request)' is inaccessible to class 'com.newrelic.agent.android.instrumentation.okhttp2.CallExtension' (declaration of 'com.newrelic.agent.android.instrumentation.okhttp2.CallExtension' appears in /data/app/appname.debug-5RvW1p6O37wA3Wu8tGTF4g==/split_lib_dependencies_apk.apk)

Is this something you've encountered before?
