Freeman Fang commented on CXF-7775:
-----------------------------------
org.eclipse.jetty.webapp.WebAppContext$Context extends
org.eclipse.jetty.servlet.ServletContextHandler$Context
and
org.eclipse.jetty.servlet.ServletContextHandler$Context extends
org.eclipse.jetty.server.handler$Context
and getContextHandler() method defined in
org.eclipse.jetty.server.handler$Context, so we cast the context to
org.eclipse.jetty.server.handler$Context should be good
> embedded jetty websocket gets ClassCastException:
> org.eclipse.jetty.servlet.ServletContextHandler$Context cannot be cast to
> org.eclipse.jetty.webapp.WebAppContext$Context
