Fields
Modifier and Type	Field and Description
`static CloseStatus`	`BAD_DATA` "1007 indicates that an endpoint is terminating the connection because it has received data within a message that was not consistent with the type of the message (e.g., non-UTF-8 [RFC3629] data within a text message)."
`static CloseStatus`	`GOING_AWAY` "1001 indicates that an endpoint is "going away", such as a server going down or a browser having navigated away from a page."
`static CloseStatus`	`NO_CLOSE_FRAME` "1006 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
`static CloseStatus`	`NO_STATUS_CODE` "1005 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint.
`static CloseStatus`	`NORMAL` "1000 indicates a normal closure, meaning that the purpose for which the connection was established has been fulfilled."
`static CloseStatus`	`NOT_ACCEPTABLE` "1003 indicates that an endpoint is terminating the connection because it has received a type of data it cannot accept (e.g., an endpoint that understands only text data MAY send this if it receives a binary message)."
`static CloseStatus`	`POLICY_VIOLATION` "1008 indicates that an endpoint is terminating the connection because it has received a message that violates its policy.
`static CloseStatus`	`PROTOCOL_ERROR` "1002 indicates that an endpoint is terminating the connection due to a protocol error."
`static CloseStatus`	`REQUIRED_EXTENSION` "1010 indicates that an endpoint (client) is terminating the connection because it has expected the server to negotiate one or more extension, but the server didn't return them in the response message of the WebSocket handshake.

  - NORMAL
```
public static final CloseStatus NORMAL
```
    "1000 indicates a normal closure, meaning that the purpose for which the connection was established has been fulfilled."
  - GOING_AWAY
```
public static final CloseStatus GOING_AWAY
```
    "1001 indicates that an endpoint is "going away", such as a server going down or a browser having navigated away from a page."
  - PROTOCOL_ERROR
```
public static final CloseStatus PROTOCOL_ERROR
```
    "1002 indicates that an endpoint is terminating the connection due to a protocol error."
  - NOT_ACCEPTABLE
```
public static final CloseStatus NOT_ACCEPTABLE
```
    "1003 indicates that an endpoint is terminating the connection because it has received a type of data it cannot accept (e.g., an endpoint that understands only text data MAY send this if it receives a binary message)."
  - NO_STATUS_CODE
```
public static final CloseStatus NO_STATUS_CODE
```
    "1005 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint. It is designated for use in applications expecting a status code to indicate that no status code was actually present."
  - NO_CLOSE_FRAME
```
public static final CloseStatus NO_CLOSE_FRAME
```
    "1006 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint. It is designated for use in applications expecting a status code to indicate that the connection was closed abnormally, e.g., without sending or receiving a Close control frame."
  - BAD_DATA
```
public static final CloseStatus BAD_DATA
```
    "1007 indicates that an endpoint is terminating the connection because it has received data within a message that was not consistent with the type of the message (e.g., non-UTF-8 [RFC3629] data within a text message)."
  - POLICY_VIOLATION
```
public static final CloseStatus POLICY_VIOLATION
```
    "1008 indicates that an endpoint is terminating the connection because it has received a message that violates its policy. This is a generic status code that can be returned when there is no other more suitable status code (e.g., 1003 or 1009) or if there is a need to hide specific details about the policy."
  - TOO_BIG_TO_PROCESS
```
public static final CloseStatus TOO_BIG_TO_PROCESS
```
    "1009 indicates that an endpoint is terminating the connection because it has received a message that is too big for it to process."
  - REQUIRED_EXTENSION
```
public static final CloseStatus REQUIRED_EXTENSION
```
    "1010 indicates that an endpoint (client) is terminating the connection because it has expected the server to negotiate one or more extension, but the server didn't return them in the response message of the WebSocket handshake. The list of extensions that are needed SHOULD appear in the /reason/ part of the Close frame. Note that this status code is not used by the server, because it can fail the WebSocket handshake instead."
  - SERVER_ERROR
```
public static final CloseStatus SERVER_ERROR
```
    "1011 indicates that a server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request."
  - SERVICE_RESTARTED
```
public static final CloseStatus SERVICE_RESTARTED
```
    "1012 indicates that the service is restarted. A client may reconnect, and if it chooses to do, should reconnect using a randomized delay of 5 - 30s."
  - SERVICE_OVERLOAD
```
public static final CloseStatus SERVICE_OVERLOAD
```
    "1013 indicates that the service is experiencing overload. A client should only connect to a different IP (when there are multiple for the target) or reconnect to the same IP upon user action."
  - TLS_HANDSHAKE_FAILURE
```
public static final CloseStatus TLS_HANDSHAKE_FAILURE
```
    "1015 is a reserved value and MUST NOT be set as a status code in a Close control frame by an endpoint. It is designated for use in applications expecting a status code to indicate that the connection was closed due to a failure to perform a TLS handshake (e.g., the server certificate can't be verified)."
