commit c3f3decd39c29d85bd5ec659ebcec853e2f337ff Author: snuyanzin <[email protected]> AuthorDate: Tue Sep 28 02:03:50 2021 +0200 [CALCITE-4602] ClassCastException retrieving from ARRAY that has mixed INTEGER and DECIMAL elements Now that we have upgraded Calcite to Avatica 1.19, which fixes [CALCITE-4602], we can add this test case to Calcite. The fix is not perfect: the ClassCastException has gone, but the resulting BigDecimal value is wrong; [CALCITE-4850] is logged for that.
