[jira] [Created] (CALCITE-2287) StackOverflowError from FlatList equals()

Zhong Yu created CALCITE-2287:

             Summary: StackOverflowError from FlatList equals()
                 Key: CALCITE-2287
             Project: Calcite
          Issue Type: Bug
            Reporter: Zhong Yu
            Assignee: Julian Hyde

The equals() method of `Flat3List` and `Flat4List` may invoke each other in an infinite loop.

See also


We found this problem when such lists are used as keys in ``; occasionally there are hashcode collisions between `Flat3List` and `Flat4List`, hence their equals() methods will be invoked.
