Michael Szodorai commented on ARTEMIS-2551:
-------------------------------------------
I am sending messages via Oracle AQ on an Oracle Database 18c Enterprise
Edition Release 18.0.0.0.0. An application server (Wildfly 18) running ActiveMQ
is set up consuming all the messages from the Oracel AQ. Further investigations
show that Oracle AQ is setting some headers to {{null }}by default for new
messages. Here is a list of JMS headers of one of the messages I received:
{code:java}
JMS_OracleHeaderOnly=null,
JMSXUserID=null,
JMSXGroupSeq=null,
JMS_OracleOriginalMessageID=null,
JMS_OracleDelay=0,
JMSXAppID=null,
JMSXRcvTimestamp=1574267857226,
JMSXGroupID=null,
JMS_OracleDeliveryMode=null,
JMSXState=0,
JMSXDeliveryCount=1,
JMS_OracleConnectionID=null,
JMS_OracleExcpQ=null,
JMS_OracleTimestamp=1574267858226
{code}
I have opened an issue for Oracle to clarify if this is the desired behavior or
not.
