public class StreamError
extends AbstractError
implements Nonza

Represents a stream error packet. Stream errors are unrecoverable errors where the server will close the underlying TCP connection after the stream error was sent to the client. These is the list of stream errors as defined in the XMPP spec:

Stream Errors

Code	Description
bad-format	the entity has sent XML that cannot be processed
unsupported-encoding	the entity has sent a namespace prefix that is unsupported
bad-namespace-prefix	Remote Server Timeout
conflict	the server is closing the active stream for this entity because a new stream has been initiated that conflicts with the existing stream.
connection-timeout	the entity has not generated any traffic over the stream for some period of time.
host-gone	the value of the 'to' attribute provided by the initiating entity in the stream header corresponds to a hostname that is no longer hosted by the server.
host-unknown	the value of the 'to' attribute provided by the initiating entity in the stream header does not correspond to a hostname that is hosted by the server.
improper-addressing	a stanza sent between two servers lacks a 'to' or 'from' attribute
internal-server-error	the server has experienced a misconfiguration.
invalid-from	the JID or hostname provided in a 'from' address does not match an authorized JID.
invalid-namespace	the streams namespace name is invalid.
invalid-xml	the entity has sent invalid XML over the stream.
not-authorized	the entity has attempted to send data before the stream has been authenticated
policy-violation	the entity has violated some local service policy.
remote-connection-failed	the server is unable to properly connect to a remote entity.
resource-constraint	the server lacks the system resources necessary to service the stream.
restricted-xml	the entity has attempted to send restricted XML features.
see-other-host	the server will not provide service to the initiating entity but is redirecting traffic to another host.
system-shutdown	the server is being shut down and all active streams are being closed.
undefined-condition	the error condition is not one of those defined by the other conditions in this list.
unsupported-encoding	the initiating entity has encoded the stream in an encoding that is not supported.
unsupported-stanza-type	the initiating entity has sent a first-level child of the stream that is not supported.
unsupported-version	the value of the 'version' attribute provided by the initiating entity in the stream header specifies a version of XMPP that is not supported.
not-well-formed	the initiating entity has sent XML that is not well-formed.

Stream error syntax:

 
 <stream:error>
   <defined-condition xmlns='urn:ietf:params:xml:ns:xmpp-streams'/>
   [<text xmlns='urn:ietf:params:xml:ns:xmpp-streams'
      xml:lang='langcode'>
   OPTIONAL descriptive text
   </text>]
   [OPTIONAL application-specific condition element]
 </stream:error>
