-------------------------------------
> Do not eagerly fill stack traces with ObjectReleaseTracker
> ----------------------------------------------------------
>
> Key: SOLR-15551
> URL: https://issues.apache.org/jira/browse/SOLR-15551
> Project: Solr
> Issue Type: Bug
> Components: Tests
> Reporter: Mark Robert Miller
> Priority: Minor
>
> Filling stack traces is really slow and so should not be eagerly done on
> every ObjectReleaseTracker#track.
> A much faster way to get a decent perf stack is the stack trace walker API &
> not necessarily walking the whole trace.
> This only fastest when everything must almost always happen and happen inline
> in a thread.
> If a different thread is filling the trace than the one capturing it, or if
> you are only filling after a failure in exceptional cases, the fastest thing
> to do is simple store a thrown exception and only trigger the fill when/if
> needed at that point.
