Which OS are you using to run this?

macdao commented 7 years ago

The first one is macOS Sierra 10.12.4 and Java 1.8.0_121. The second one is openjdk(Image ID 828eb773e77c) in Docker. The second way happened every time.

macdao commented 7 years ago

see #195, the problem is MocoProxyTest.should_proxy_with_request_method which block the tests.

dreamhead commented 7 years ago

The test is blocked because of too many connections.

Check the following commit to "try to reuse connection" https://github.com/dreamhead/moco/commit/5de3506a76c1de2bf889540a22a236d6f8e9e218

macdao commented 7 years ago

Cool!

I want to understand it. The new commit use a pool http client instead of HttpClients.createDefault() when do forward. It looks like t always create a new http client in doForward method before the new commit. Why the new http client blocked before? I cannot understand.
