MutablePublicArray

Nonzero-length arrays are mutable. Declaring one public static final indicates that the developer expects it to be a constant, which is not the case. Making it public is especially dangerous since clients of this code can modify the contents of the array.

There are two ways to fix this problem:

1. Refactor the array to an ImmutableList.
2. Make the array private and add a public method that returns a copy of the private array.
