Question

I am running Selenium test cases by using Callable threads and I am getting java.lang.NoSuchFieldError: LINUX exception at executerService.submit(callable).get() this line when I tried to run test case.

My test cases are Callable and for every test case I create callable object and submit it, but after submit I am getting

Root Cause
The referred Platform.LINUX field in the source is absent.

Fix
You need to upgrade to the latest version of selenium jar.
