Chris M. Hostetter commented on SOLR-16983:
-------------------------------------------
I believe the most straightforward fix is to simply remove the
{{ObjectReleaseTracker.clear()}} call from {{SolrTestCaseJ4}} – that code
probably should have been removed long long ago whenever the "check" logic got
moved to the {{SolrTestCase}} base class.
But based on a quick check (w/o trying multiple seeds, or running nightly)
fixing this test framework bug is going to cause at least ~17 test classes to
start failing – tests that should have been failing for a long time, either
because the test doesn't properly cleanup, or because the code being tested has
an underlying object leak bug.
I don't think i have the bandwidth or energy to try and fix all of these – so
help would be appreciated from anyone that wants to help up and try to tackle
this.

> {{SolrTestCase}} has a {{@ClassRule}} named {{solrClassRules}} which calls
> {{ObjectReleaseTracker.clearObjectTrackerAndCheckEmpty()}} in it's
> {{afterIfSuccessful()}} method to ensure that any objects which use
> {{ObjectReleaseTracker}} are correctly released (ie: closed)
> _*...BUT...*_
> {{SolrTestCaseJ4}} has an {{@AfterClass}} method named
> {{teardownTestCases()}} which calls {{ObjectReleaseTracker.clear()}} _before_
> the {{afterIfSuccessful()}} method of it's parent class's {{solrClassRules}}
> gets to run.
> ... Which means that {{ObjectReleaseTracker}} is completley useless in every
> test that descends from {{{}SolrTestCaseJ4{}}}.
