okhttp: Strict Mode Error: Explicit termination method 'close' not called

Wounder if anyone else has seen this strict mode violation, it could be my own code but if it is I can’t see how.

E/StrictMode: A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.

I have similar issue with v 3.11.0, see in logs this error:

I’m not sure, but everything seems to be working.

Please don’t call cache.close() until you’re completely done with your response cache.
