High CPU usage when using hawtio

Test case is attached in a docker container. Steps to reproduce are the following: ------------------------------ 1- Download attached "docker-hawtio-highcpu.zip" (caution, big file ~800M) 2- Unzip it 3- run: ./docker.sh (this will create your container, start it, and give you a command prompt) 4- At the prompt received from 4, run: ./setup.sh (this will unzip both IBM java and AM-Q to /opt, then will start AM-Q) 5- In another command prompt, execute: ./dockerexec.sh (this will just give you another login prompt to the same container), then run: top (to monitor AM-Q java process 6- In your client machine, start three browser instances, and point them to <machine-ip>:18181 (18181 is being forwarded to 8181 of the docker container). Open the ActiveMQ tab 7- Refresh the browser pages. Each time it is done, CPU spike to ~500% CPU
