wct tests failing with local selenium server standalone setup

[ranadeepak]

Hi,
I am trying to run the wct tests on my local machine. The versions of libraries I am using are:
wct: 6.7.1
polymer: 2
selenium standalone: selenium-server-standalone-3.12.0.jar
java version: 10.0.1
OS: windows 7, 64 bit
chrome browser: Version 67.0.3396.99

I have configured the webdrivers versions manually by copying the drivers and jar from the following locations:
chromedriver: https://chromedriver.storage.googleapis.com/2.40/chromedriver_win32.zip
iedriver: https://selenium-release.storage.googleapis.com/3.12/IEDriverServer_x64_3.12.0.zip
firefox: https://github.com/mozilla/geckodriver/releases/download/v0.20.1/geckodriver-v0.20.1-win64.zip
edgedriver: https://download.microsoft.com/download/F/8/A/F8AF50AB-3C3A-4BC4-8773-DC27B32988DD/MicrosoftWebDriver.exe
selenium: https://selenium-release.storage.googleapis.com/3.12/selenium-server-standalone-3.12.0.jar

Then I ran the command: wct -l chrome --skip-selenium-install

This command is failing with following trace:

FWIW, WCT doesn't work with Java 10, you need Java 8. See #405. However, the error you are getting does not fit the error I was getting but perhaps it's due to the mac/windows difference?

switching back to java 8 and some minor proxy changes did the trick. Thanks @rjsteinert
