The web console invokes the "listConsumers" operation on the ActiveMQServerControl [1] which you can see here [2].
This looks like a bug on the broker when it tries to sort the results based on a particular column. The differences between the IDs returned by listAllConsumersAsJSON vs listConsumers is caused by the differences in the way they're implemented on the broker. The former returns org.apache.activemq.artemis.core.server.ServerConsumer#getID and the latter returns org.apache.activemq.artemis.core.server.ConsumerInfo#getSequentialID. Any information you can provide about how to reproduce this problem would be greatly appreciated. Thanks!
