Michael McCandless commented on LUCENE-4488:
--------------------------------------------
Hmmm when I run:
{noformat}
ant test -Dtests.nightly=true -Dtestcase=TestIndexWriterOnJRECrash
-Dargs="-XX:+HeapDumpOnOutOfMemoryError" -Dtests.leaveTemporary=true
{noformat}
in lucene/core, I can't find any heap dump file created. Wasn't this the test
that prevents us from turning on heap dumps? (Or is it creating hs_err
somewhere? But it's tiny ... I can't find it either ...).
> Jenkins builds aren't saving heap dumps anymore

> Our Jenkins builds used to save heap dumps, which is really useful for
> tracking down OOMEs that are hard to reproduce: sometimes these OOMEs are due
> to real issues.
> From the thread it sounds like it's easy to fix TestIndexWriterOnJRECrash to
> not dump ...
