I've only test one request after another. Win7 64bit. Server is another B4J server(4.20 ,released mode, localhost) return text "ok"
OkHttp:
Debug mode: stop to response after 100-300 requests. Jobdone event not fire ( even after timeout)
Release mode : 50% chance to stop at about 2000 or 3000 requests (Stop testing after 5000 req)
HttpClient works fine after 10000 reqs.
Maybe it's caused by my computer. I've tested in Vmware Ubuntu 14.04, similar result with OkHttp
