Robert Muir created SOLR-14000:
----------------------------------
Summary: clean up more static field leaks in tests
Key: SOLR-14000
URL: https://issues.apache.org/jira/browse/SOLR-14000
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Robert Muir
See build https://jenkins.thetaphi.de/job/Lucene-Solr-8.x-Windows/577/ for
example, stuff like this:
{noformat}
Stack Trace:
junit.framework.AssertionFailedError: Clean up static fields (in @AfterClass?)
and null them, your test still has references to classes of which the sizes
cannot be measured due to security restrictions or Java 9 module encapsulation:
- private static org.apache.solr.prometheus.scraper.SolrStandaloneScraper
org.apache.solr.prometheus.scraper.SolrStandaloneScraperTest.solrScraper
- private static org.apache.solr.client.solrj.impl.HttpSolrClient
org.apache.solr.prometheus.scraper.SolrStandaloneScraperTest.solrClient
{noformat}
Looks like security manager issue, but its not, its just static leaks in tests.
Its just that the thing they leak can't be inspected to see how "big" the leak
is (apparently the objects were below some threshold before).
We should just plug the leaks, null them out in AfterClass.
