Bug 57969

Under high load, given a @ServerEndpoint like


@ServerEndpoint(value="/websocket/{key}", configurator=MyConfigurator.class)
public class ExecutionMonitoringEndpoint{
...
@OnMessage
public void onMessage(@PathParam("key") String key, String payload) {
   ...
}
}
//where MyConfigurator is used to only inject a custom property like ServerEndpointConfig.conf.getUserProperties().put(...);

we noticed that the captured PathParam ("key" in this case) was sometimes mixed up with another concurrent request - causing double subscriptions in our pub/sub application.


Changing the above to

@ServerEndpoint(value="/websocket/{key}", configurator=MyConfigurator.class)
public class ExecutionMonitoringEndpoint{
...
@OnMessage
public void onMessage(Session session, String payload) {
  String key = session.getPathParameters().get("key");
}
}

fixed the problem.
