@marcosflobo : I tried reproducing this issue but couldn't reproduce it. For me, it seems to be running okay. Could you please check my reproducer project to see what I'm missing? What JUnit version are you using? Do you have any kind of exclusion for okhttp in your project?

I encountered this issue in a gradle project and was able to resolve it by adding com.squareup.okhttp3:mockwebserver as a test dependency.
