[dreamhead]

Which OS are you using to run this?

[macdao]

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]

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

[dreamhead]

The test is blocked because of too many connections.

Check the following commit to "try to reuse connection"
5de3506

[macdao]

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.
