Description
In some environments an OOM can arise due to excessive use of finalizers. We need an ability to diagnose this type of issue. One idea is to add a -finalizerinfo or -finalizerhisto option to jmap so that the tool prints a histogram of the objects in the finalizer queue.

EVALUATION

As part of the OOM handling work (6173515) we have created a -finalizerinfo option for jmap. This prints a class-wise histogram of the object awaiting finalization.
