[ https://issues.jboss.org/browse/WFLY-5364?page=com.atlassian.jira.plugin.... ] Jan Stourac updated WFLY-5364: ------------------------------ Description: According to [RFC7540|https://tools.ietf.org/html/rfc7540] frame types DATA, PRIORITY and HEADERS are associated with particular data stream, therefore if its stream id is 0 this should be processed as PROTOCOL_ERROR. Similarly frames of types GOAWAY and SETTINGS must not be associated with particular stream id other than 0, if so then PROTOCOL_ERROR should be raised. With current implementation this requirement is not checked causing discrepation against RFC specification. was: According to [RFC7540|https://tools.ietf.org/html/rfc7540] frame types DATA and HEADERS are associated with particular data stream, therefore if its stream id is 0 this should be processed as PROTOCOL_ERROR.
