> Calcite hung on SqlPrettyWritter after 4 or 5 successful query executions

> Key: CALCITE-1720
> URL: https://issues.apache.org/jira/browse/CALCITE-1720
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.11.0
> Environment: JRE v1.8, Oracle
> Reporter: Lei Wei
> Assignee: Julian Hyde

> Hi Julian,
> We're running POCs of calcite and avatica. We've built a standalone server to
> connect oracle and accept Avatica jdbc calls. We try to build a complete
> query flow from Client -> AvaticaJDBC -> Calcite -> Oracle. We're able to
> successfully send sql calls from Squirrel and a simple java test code, and
> received resultset successfully. However, after 4 or 5 successful calls,
> Calcite hung and the log stopped at SqlPrettyWritter. We couldn't run any
> more tests unless we restarted the standalone server.
> After we turning on the TRACE log, we saw the logs stops at SqlPrettyWriter.
> Has anyone ever reported this issue?
