NPE in HighlightMethodUtil#isWeaker

Introduction. I am very surprised that such an error was not there before. About a year already working plug and there was no error.

In if statement for plugins with implicit access modifiers this code produce NPE.
Our modifier list has protected modifier on PsiMethod without explicit keyword.

Code

       if (modifierList.hasModifierProperty(PsiModifier.PACKAGE_LOCAL)) {
          textRange = method.getNameIdentifier().getTextRange();
        }
        else {
          PsiElement keyword = PsiUtil.findModifierInList(modifierList, accessModifier);
          textRange = keyword.getTextRange(); // here NPE
        }
}

java.lang.NullPointerException

Can you fix this?
Like this:

       if (modifierList.hasModifierProperty(PsiModifier.PACKAGE_LOCAL)) {
          textRange = method.getNameIdentifier().getTextRange();
        }
        else {
          PsiElement keyword = PsiUtil.findModifierInList(modifierList, accessModifier);
          textRange = keyword == null ? method.getNameIdentifier().getTextRange() : keyword.getTextRange(); // here NPE
        }
}

Or something else
