[jira] [Updated] (SOLR-16548) CaffeineCache seems to be not working in 9.0 and later
[ https://issues.apache.org/jira/browse/SOLR-16548?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shawn Heisey updated SOLR-16548:
--------------------------------
Description:
I am seeing evidence that CaffeineCache is not working correctly.
To reproduce:
* download 9.0.0, extract it, and cd into the extracted directory. Do this on a system that is not already running any software (including Solr) that listens on ports 8983 or 7574.
* Start the cloud example with this command:
* SOLR_JETTY_HOST=0.0.0.0 bin/solr -e cloud -noprompt
* Visit this URL in your browser, substituting "hostname" with a name or IP address that is correct for your environment:
*
** [http://hostname:8983/solr/#/gettingstarted_shard1_replica_n6/plugins?type=cache&entry=filterCache]
* In another tab, visit this URL, substituting hostname again:
[http://hostname:8983/solr/gettingstarted_shard1_replica_n6/select?q=*:*&fq=id:test]
* On that tab, hold shift and press the reload button. Do this several times.
* Go back to the first tab and reload the page.
You will see that size, lookups, and inserts are 1, but hits is zero. Both hits and lookups should be increasing with every shift-reload on the other tab.
Is this a valid test? I think it should be.
I am running with OpenJDK 11. For 9.1.0 and 9.2.0-SNAPSHOT, I am building with OpenJDK 11 as well. This should mean that the caffeine-related mitigation for crashing on Java 17 is not enabled.
On branch_9x, I have tried downgrading Caffeine from 3.1.1 to 3.0.5 and also to 2.9.2 and it did not change the behavior, so I don't think the problem is in Caffeine.
