When looking at the JFC files in build 23, at least 3 events are available but not listed in any of the JFC files. They should be there (probably controlled by a control element) so there is an easy way to turn them on/off. The 3 events are vm/gc/detailed/object_count (which JMC uses for building the Object Staticsics tab) and java/object_alloc_in_new_TLAB and java/object_alloc_outside_TLAB which we use to build the Allocations Tab.
