I think that is the JVM implementation issue. I am not using that JVM, but MXBean(such as java.lang.management.MemoryUsage) is the official and standard way to get this. If you want to change, feel free to change the source codes. It is not hard. I am not sure what your issue is. Other APM, most likely commercial product, is not our concern.
