com.groupon.seleniumgridextras.grid.servlets.ProxyStatusJsonServlet] cannot be instantiated

Hi,

I am unable to enable the servlet in Selenium Grid 3.11, Window 10

WARN [ExtraServletUtil.createServlet] - The specified class : com.groupon.seleniumgridextras.grid.servlets.ProxyStatusJsonServlet] cannot be instantiated com.groupon.seleniumgridextras.grid.servlets.ProxyStatusJsonServlet]

Seems to be working with webdriver 3.9.0 but not with webdriver 3.10.0 and 3.11.0.

Running the hub with Selenium Grid Extras 2.0.2 on a Ubuntu 16.04.3 LTS:

/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java -jar "/opt/selenium/jars/SeleniumGridExtras-2.0.2-SNAPSHOT-jar-with-dependencies.jar"

Grid extras config file:

"webdriver": {
"version": "3.11.0"
},
"hub_additional_classpath": ["/opt/selenium/jars/extension-proxy-1.0.jar"]

Hub json file with HubRequestsProxyingServlet needed for Sikuli with Selenium Grid:

"servlets": ["com.groupon.seleniumgridextras.grid.servlets.ProxyStatusJsonServlet","io.sterodium.extensions.hub.proxy.HubRequestsProxyingServlet"],
"capabilityMatcher": "io.sterodium.extensions.capability.CustomCapabilityMatcher",

Hub log with webdriver 3.11.0:
