Support error codes 1012 (Service Restart), 1013 (Try Again Later) and 1014 (Bad Gateway)

Hi,

Using Java-WebSocket 1.3.7 as a client I encountered an InvalidDataException "Trying to send an illegal close code!" when the server sends an 1013 error code (Try Again Later). Looking at the CloseFrame.java
class it seems the error codes 1012, 1013 and 1014 are not supported yet and trigger an exception on the client side.

Hello @ebourg,

thank you for your issue!

These close frames are not part of the official RFC and were added later.
Could you tell me which endpoints use these close codes?

The Java WebSocket API 1.1 has the codes 1012 and 1013 which are implemented in application servers such as Tomcat or Jetty. The code 1014 is described on the Mozilla Developer Network.
