[jira] [Created] (CALCITE-699) In Avatica, synchronize access to Calendar

Julian Hyde created CALCITE-699:
-----------------------------------

             Summary: In Avatica, synchronize access to Calendar
                 Key: CALCITE-699
                 URL: https://issues.apache.org/jira/browse/CALCITE-699
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


The Calendar class is not thread-safe. Some JDBC methods accept Calendar objects from the client. We must  synchronize on this Calendar in case the client is using the Calendar elsewhere.

Avatica also creates Calendar objects internally. Access to those calendars does not need to be synchronized, but they are often passed into methods that accept client Calendars, and will get synchronized anyway.
