java.util.zip.DataFormatException：錯誤的數據檢查

Question

我在加載JSF頁面時遇到了下面提到的錯誤。頁面被成功加載，並且頁面上的所需操作也完成，但是出現此錯誤。

JSF頁面包含標籤面板，如果我嘗試包括從現有的項目包括項目的一些項目中，錯誤出現。以下是列表的XHTML。

<a4j:outputPanel id="selectItems"> 
    <div id="div_selectItems" class="scroll_container"> 
     <s:div styleClass="dialogueAttribute"> 
      <rich:listShuttle sourceValue="#{itemReportEditor.itemsList}" 
           targetValue="#{itemReportEntry.itemReportData}" 
           var="items" 
           listsHeight="28em" 
           sourceListWidth="45em" 
           targetListWidth="45em" 
           sourceCaptionLabel="Available Items" 
           targetCaptionLabel="Included Items" 
           removeAllControlLabel="Remove all" 
           removeControlLabel="Remove" 
           copyControlLabel="Add" 
           copyAllControlLabel="Add all" 
           fastOrderControlsVisible="true" 
           orderControlsVisible="true" 
           converter="#{itemReportEditor.itemReportDataModelConverter}"> 
       <rich:column> 
        <f:facet name="header"> 
         <h:outputText title="Performance item name" 
             value="Name"/> 
        </f:facet> 
        <h:outputText value="#{items['itemName']}"></h:outputText> 
       </rich:column> 

       <rich:column> 
        <f:facet name="header"> 
         <h:outputText title="Performance Item Protocol" 
             value="Protocol"/> 
        </f:facet> 
        <h:outputText value="#{items['protocol']}"></h:outputText> 
       </rich:column> 

       <a4j:support event="onlistchanged" 
          action="#{itemReportEntry.updateItemsList()}" 
          reRender="la" 
          oncomplete="resizeScrollBox2();" 
          status="workingStatus" 
          eventsQueue="ajaxQueue"/> 
      </rich:listShuttle> 
     </s:div> 
    </div> 
</a4j:outputPanel> 

我試圖使用清單班車從左手邊一些項目添加到右側，我收到以下異常（僅在FireFox瀏覽器，沒有觀察到在谷歌瀏覽器這個問題）的日誌（能夠正確應用所有更改，只是得到以下例外）。我的FireFox版本是35.0.1

使用谷歌搜索我發現「問題似乎是像'！'這樣的字符由FireFox轉換爲'％21'，以下過濾器會將％21轉換回'！'這樣的資源可以在服務器」

在我的情況可以發現，我剛開始在日誌中的異常，但所有的源加載成功

爲了消除異常，我添加了過濾器

即使我收到了這樣的例外。 產生的原因：java.util.zip.ZipException：不正確的數據校驗 在java.util.zip.InflaterInputStream.read（InflaterInputStream.java:147）

但在我的情況下，根本原因將其IAM試圖流讀取使用flate編碼器壓縮，因此試圖解壓縮的流是InflaterInputStream。

在我的情況下發生的是出現在最後一個字節是不是EOF參數的實際數據中的數據，EOF參數存在最後一個字節之前某處流。因此，當數據流傳遞塊數據的最後一個字節時，無法找到eof，從而引發錯誤的數據檢查。

也許驗證它在你的最終...它可以在你到底有同樣的問題了。
