AccountManager imports(Credentials credentials, String password) 方法153行是不是有问题

[s6056826]

	String hexAddress = AddressType.User.normalize(credentials.getAddress());
	Address address = new Address(hexAddress, this.networkId);
	if (this.exists(address)) {
		return Optional.empty();
	}
	
	this.createKeyFile(password, credentials.getEcKeyPair());
	
	return Optional.of(address);

这个address解密之后有地址，你这个if (this.exists(address)) 判断有地址然后制空吗，这正确吗，不应该是if (!this.exists(address))
