WebDriver-driven Firefox with browsermob-proxy cannot be closed within selenium-server 2.30.0 version

[lukeis]

Originally reported on Google Code with ID 5415

Repro Steps:
1. Start FirefoxDriver with browsermob-proxy 
2. Then, navigate to taobao.com
3. Try to quit driver in  teardown method (Tried both in TestNG and junit)

Actual Result: 
The firefoxdriver instance  should be closed automcaticallly. But instead of that,
the firefox doesnot quit as expected. 

Fore more information: 
1. I also tried to quit FirefoxDriver instance without proxy configured like above.
And the firefoxdriver instance closed smoothly. 
2. Then, I tried to debug this issue. The debug info turns out that after running @Test
method, the firefoxdriver instance is still alive. And it's level is FINE. But after
entering the teardown method, the firefoxdriver instance becomes to be a NULL object.

Selenium version: 2.30.0
OS: Window XP
Browser: Firefox
Browser version: 19.0.2

Pls help to locate whether this is a selenium issue?

Attached is my codes:

I forgot above that IE8 and Chrome works fine in this senario.

It's quite suspicious that IE and Chrome work, they should not!

Because you use a local 'driver' variable in the test method, and your static 'driver'
field is never assigned.
