Julian> allocate a new object per request Josh> The Meta implementation inside of the Avatica server is a singleton,
Julian, I don't think singletones can be allocated per request. I don't think final fields of singletones can be changed on a per-request basis. What's your suggestion then? I've created https://issues.apache.org/jira/browse/CALCITE-2853 It looks like the issue was there for ages, so it does not look like a release blocker, however the bug does break CI, and I'm tired of getting "build's broken" mails from Apache Jenknis, especially after I commit an innocent fix.
