HubRequestsProxyingServlet cannot be instantiated after upgrading from Selenium 3.7.0 to 3.11.0 #65

The Selenium extensions were working fine on v3.7.0, but after upgrading to v3.11.0 I'm getting HubRequestsProxyingServlet cannot be instantiated when starting the hub. I've built & deployed the latest selenium-grid extensions.

Stack trace from hub startup:

Tested some previous versions and it's working in v3.9.1

v3.10.0 server didn't start due to a NPE:

For 3.11.0 try to change hubConfig.json propetry from

"servlets": ["io.sterodium.extensions.hub.proxy.HubRequestsProxyingServlet"]

to

"servlet": "io.sterodium.extensions.hub.proxy.HubRequestsProxyingServlet"

Yup, that fixed it.

Many Thanks.
