Eugene Zimichev created CALCITE-629:
---------------------------------------
Summary: Can't use extended version of CalcitePrepareImpl with
JDBC Driver
Key: CALCITE-629
URL: https://issues.apache.org/jira/browse/CALCITE-629
Project: Calcite
Issue Type: Bug
Affects Versions: 1.0.0-incubating
Reporter: Eugene Zimichev
Assignee: Julian Hyde
Constructor of CalciteConnectionImpl directly uses field Driver#prepareFactory,
although Driver class provides protected method that can redefine it.
Because of field hiding user can't register a custom extension of
CalciteConnectionImpl.
Proposed fix - use createPrepareFactory method instead of field access.
