Use of unnecessary "^ true" for boolean expressions

[bagipro]

Hi,
I've noticed that thing in master and type-inference-wip branches. For example
com.paypal.android.p2pmobile.wallet.banksandcards.utils.EnterCardFragmentUtils

    public static boolean isCardCSCValid(@android.support.annotation.Nullable com.paypal.android.foundation.wallet.model.FinancialInstrumentMetadataDefinition financialInstrumentMetadataDefinition, java.lang.String str) {
        boolean z = false;
        if (financialInstrumentMetadataDefinition == null) {
            return false;
        }
        com.paypal.android.foundation.wallet.model.FinancialInstrumentMetadataAttribute cvv = financialInstrumentMetadataDefinition.getCvv();
        if (cvv == null) {
            return true;
        }
        if (android.text.TextUtils.isEmpty(str)) {
            return cvv.isRequired() ^ true; // <<<
        }

It seems that booleanExpr ^ true is useless and can be removed, but booleanExpr ^ false could be replaced with !booleanExpr
