Have you confirmed (via techniques such as the ones described in https://www.cyberciti.biz/faq/linux-which-process-is-using-swap/) that the ActiveMQ process is the one whose pages are getting swapped?
Also, what does top show your buffer usage (i.e. Linux using memory to buffer disk writes for performance reasons) during this period of time? Linux has an OS setting (vm.swappiness) that will let you control how willing the OS is to swap out pages. You could adjust this value to make paging less likely (or forbid it entirely) if you wanted.
