Description

While looking at how a tablet server processes constraint violations, I happened to look into Mutation's hashCode implementation:

  @Override
  public int hashCode() {
    return toThrift(false).hashCode();
  }

Clicking through to TMutation hashCode finds this gem:

  @Override
  public int hashCode() {
    return 0;
  }
