Okhttp: StackOverflowError on Android 4.4 and below

[MaciejPachciarekSMT]

I get StackOverflowError on Android 4.4 (tested on 6 devices) and below. On 5.0 works perfect. I have around 8 calls one by one, first few (3-4) works great and on next I get error. I add 2 custom Interceptor. It added only one (check on interceptors on RealInterceptorChain class). I used okhttp 3.9.0 with retrofit 2.3.0 and rjava 2.1.5

I don't think this counts as an OkHttp bug. The combination of libraries you are using unfortunately overflows the stack on older devices. Can you post in stackoverflow (no pun intended).
