Describe the solution you'd like.
Support for these events. They should provide count and memory size per object type after a GC has completed.
Describe who do you think will benefit the most.
GraalVM users that use JFR to debug memory leaks, and allocation related issues.
Describe alternatives you've considered.
Heap dumps are an alternative approach to inspecting objects on the heap. However, jdk.ObjectCount and jdk.ObjectCountAfterGC have the advantage of continuously providing a data points over time. It should also be quicker to emit these events than do a full heap dump.
