> These are caused by {{sun.nio.ch.ServerSocketAdaptor}} becoming a non-public class in JDK 11 (if not earlier).
> It can be fixed simply by having {{IntrospectionSupport.setProperty}} call {{setter.setAccessible(true)}} before it invokes any methods on it.
> Otherwise we find our local broker runs perfectly fine.
