Strange Address Sizes on clustered topics.

Hello,

We are seeing some strange AddressSizes in JMX for simple clustered topics. The problem was observed on 2.12.0 in production but can also be reproduced on 2.14.0. I set up a 3-node cluster (Sample broker.xml) attached. The test program creates multiple clustered topic consumers. A publisher sends a message every few seconds. The JMX console shows a strange address size on one of the nodes. Easy to reproduce with the attached test program. Seems to be fine with queues. 

Thank you for help in advance.TestClusteredTopic.javabroker.xml
