-----------------------------------
Summary: CaffeineCache seems to be not working in 9.0 and later
Key: SOLR-16548
URL: https://issues.apache.org/jira/browse/SOLR-16548
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Affects Versions: 9.0, 9.1, 9.2
Reporter: Shawn Heisey
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.
