问题
I have the same tests, the same selenium-server-standalone (2.43.1) and chromedriver (2.10). I have only functional tests (no unit tests). My Chrome is at version 37. My OSX is at version 10.9.5. Java version is 1.7.0_51 (Java 7 update 67).
When I run tests a new Chrome instance is opened with an empty tab:
- With intern 1.7.0 tests start in less then 10 seconds.
- With intern 2.1.1 tests start in 55-60 seconds.
Selenium logs look like this (when run by intern 2.1.1):

My intern configuration looks like:
define({
proxyPort: 9000,
proxyUrl: 'http://localhost:9000/',
capabilities: {
'selenium-version': '2.43.1'
},
environments: [
{ browserName: 'chrome'}
],
maxConcurrency: 3,
tunnel: 'NullTunnel',
loader: {},
suites: [],
functionalSuites: 'tests/all_functional',
reporters: ['console'],
excludeInstrumentation: /^tests\//
});
I tried to use Selenium 2.42.2 with chromedriver 2.10 and chromedriver 2.9 but the results are similar.
Update 1
The same problem persist with OSX 10.10, Java 1.7.0_51 (Java 7 update 71), chromedriver 2.11 and Chrome 38.0.2125.104.
Update 2
I started looking at why there is such a big delay between HttpContext and ServletHandler startup. Debug shows that New random session seed takes that long time (5 sec). It seems that all errors that take longer time have time that is multiple of 5 (5 sec, 10 sec and 25 sec).
On other Unix systems this problem was solved by replacing /dev/random by /dev/urandom but on OSX there should be no difference between them. I tried feeding /dev/random with data while selenium was running but it didn't help.
Running with sudo gives the same result.
Specifying -Djava.security.egd=file:///dev/urandom gives the same result.
Update 3 On a new machine problem disappeared. And as I have no more the old machine - the answer will remain a mystery.
The only thing that I think could be different between these machines is JDK.
回答1:
I ran into this issue on macOS Sierra when using selenium-standalone-server 2.42.2 and chromedriver 2.25. I tried several version combinations of the two while using java version 1.8.0_91 to no avail.
The issue was resolved by reverting to a previous version of java, java version 1.8.0_45. Not the best solution, so I'm using http://www.jenv.be/ to go back and forth when I need to. This does not identify the issue's root cause but I hope this workaround helps someone, took me a while to find it.
