HPjmeter 4.3 User's Guide

Guidelines

• Escalating numbers of unfinalized objects can indicate that the finalizer queue is growing,

with associated objects holding increasing space in the heap.

Details

• Some or many of the objects in a finalizer queue may no longer be needed by the program

and are waiting to be finalized and then collected.

• Check to see if the finalize () method in your application is being called at appropriate

times and frequency.

• Profiling with –Xeprof will help you to obtain details about the number of unused finalizers

in the heap.

• Use the monitoring or profiling thread histogram to check the state of the finalizer thread

during the recorded period.
