-----------------------------------------
Summary: 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
Security Level: Public (Default Security Level. Issues are Public)
Components: Tests
Reporter: Mark Robert Miller
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.
