Testing by sending a lot of messages by brokers, about 200,000. We have noticed
that the count of messages in the queue is broken. When we finished consuming
messages, the website showed us that we had 22 messages. We checked if they
were scheduled and using the jolokia api it told us that we had no scheduled
messages.
Checking the log we see that there are 22 null pointer exception with:
WARN [org.apache.activemq.artemis.core.server] AMQ222225: Sending unexpected
exception to the client
java.lang.NullPointerException: Cannot invoke
"org.apache.activemq.artemis.core.server.MessageReference.getSequence()"

ideas?
