Answer 1

INFORMATION: Attempting bi-dialect session, assuming Postel's Law holds true on the remote end
As per the discussion Attempting bi-dialect session, assuming Postel's Law holds true on the remote end thread 'webdriver dispatcher' panicked at 'index out of bounds: the len is 0 but the index is 0 this issue was reproducible with Selenium Client v3.0.0-beta3 released on 2016-09-01 14:57:03 -0700 with GeckoDriver.
Simon in a comment mentioned that:
The root cause was a ClassCastException. We now catch that exception, log the thing that we were trying to parse and continue with other attempts to complete the handshake. The fix was available in Selenium Client v3.0.0-beta4.
