> Problem unveiled by CALCITE-3535, and also separately by CALCITE-3576.
> When CALCITE-3535 was committed, it made {{MaterializationTest#testJoinMaterialization8}} and {{MaterializationTest#testJoinMaterialization9}} change their execution plan from hashJoin to nestedLoopJoin. This caused an exception
> {code}
> java.lang.ClassCastException: java.lang.String$CaseInsensitiveComparator cannot be cast to java.lang.String
> {code}
> which seems unrelated to CALCITE-3535 (or CALCITE-3576), so the tests were temporarily disabled.
> The goal of this ticket is to investigate the root cause of this issue and re-activate both tests.
