-----------------------------------
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.
