---------------------------------------
vkorukanti opened a new pull request #1380: ARROW-1877: Fix incorrect equals
method in JsonStringArrayList
URL: https://github.com/apache/arrow/pull/1380
Currently it uses containsAll which could return wrong results.
Ex. e1: [true, true, false], e2: [true, false, false].
Remove the equals method and fallback to super class method
which has the correct implementation.
