Quorum - 無法從另一個公共契約中讀取一個公共契約的狀態

我正在執行 truffle 的 7nodes 仲裁範例，範例功能按預期工作。0但是，當我創建一個公共契約來訪問另一個公共契約的狀態時，即使不是這樣，我也會得到一個返回值。奇怪的是，合約能夠設置被呼叫合約的狀態。我在下面添加了詳細資訊。有人可以告訴我在這裡做錯了什麼嗎？

geth version: 1.7.2-stable truffle version: v4.1.7 solc-js version: v0.4.23

公共契約 1：

pragma solidity ^0.4.17;

contract PublicStorage {
 uint public storedData;

 function PublicStorage(uint initVal) public {
   storedData = initVal;
 }

 function set(uint x) public {
   storedData = x;
 }

 function get() constant public returns (uint retVal) {
   return storedData;
 }
}

公共契約 2：

pragma solidity ^0.4.17;

import './PublicStorage.sol';

contract PubStorageReader {
 uint public storedData;
 PublicStorage publicStorage;

 function PubStorageReader(uint initVal, address publStorageAddr) public {
   storedData = initVal;
   publicStorage = PublicStorage(publStorageAddr);
 }

 function setPublic(uint x) public {
   publicStorage.set(x);
 }

 function getPublic() constant public returns (uint publicRetVal) {
   return publicStorage.get();
 }
}

部署腳本：

deployer.deploy(PublicStorage, 102)
       .then(function() {
           return deployer.deploy(PubStorageReader, 202, PublicStorage.address);
       });

呼叫：

> PublicStorage.deployed().then(function(instance) { return instance.get(); })
{ [String: '102'] s: 1, e: 2, c: [ 102 ] }

> PubStorageReader.deployed().then(function(instance) { return instance.getPublic(); })
{ [String: '0'] s: 1, e: 0, c: [ 0 ] }

> PubStorageReader.deployed().then(function(instance) { return instance.setPublic(2); })
{ ... }

> PublicStorage.deployed().then(function(instance) { return instance.get(); })
{ [String: '2'] s: 1, e: 0, c: [ 2 ] }

現在在 testrpc 上執行相同的程式碼會按預期讀取狀態。這有什麼錯誤？

我試過最新的松露（v5.0.9）和solc v0.5.0，它適用於那些：

MacBook-Pro:truffle-workspace satpal$ truffle version
Truffle v5.0.9 (core: 5.0.9)
Solidity v0.5.0 (solc-js)
Node v8.11.4
Web3.js v1.0.0-beta.37

完全相同的問題。

我還注意到，如果您使函式“getPublic()”不是常量/視圖，則執行會耗盡氣體。
