    Description

      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

      java.lang.ClassCastException: java.lang.String$CaseInsensitiveComparator cannot be cast to java.lang.String
      

      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.
