Rule Set:unnecessary.html#UselessParentheses
Code Sample demonstrating the issue:
These are incorrectly reported as useless parentheses:
return (mNumber != null ? mNumber.equals(team.mNumber) : team.mNumber == null)
&& (mKey != null ? mKey.equals(team.mKey) : team.mKey == null)
&& (mTemplateKey != null ? mTemplateKey.equals(team.mTemplateKey) : team.mTemplateKey == null)
&& (mName != null ? mName.equals(team.mName) : team.mName == null);
Removing them would result in nested ternary operations returning an incorrect boolean.
