Alvin Lin created AMQ-7012: ------------------------------ Summary: Misleading error in org.apache.activemq.transport.stomp.ProtocolConverter Key: AMQ-7012 URL: https://issues.apache.org/jira/browse/AMQ-7012 Project: ActiveMQ Issue Type: Bug Affects Versions: 5.15.4 Reporter: Alvin Lin
>From time to time I see the following log line for STOMP: {{2018-07-17 07:31:22,204 | WARN | Exception occurred processing: <Unknown> -> org.apache.activemq.transport.stomp.ProtocolException: No subscription matched. | org.apache.activemq.transport.stomp.ProtocolConverter | ActiveMQ NIO Worker 1186}} The misleading part is "<Unknown>", the unknown is suppose to be the STOMP's action word (SEND, SUBSCRIBE etc). The problem seems to be {code:java} org.apache.activemq.transport.stomp.ProtocolConverter.safeGetAction(){code} that is comparing the STOMP action word with constants defined in {code:java} org.apache.activemq.transport.stomp.ProtocolConverter.Stomp.Commands{code} But for subscribe and unsubscribe the constants are defined as "SUB" and "UNSUB" which does not match the actual STOMP action verbs. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
