打开HFT纪事图，在Websphere上找不到类异常

Question

我试图使用OpenHFT ChronicleMap，代码在Tomcat中运行，但是在Websphere中失败，有以下错误(如下)

注意:这不是在Tomcat中发生的，只发生在Websphere中。

代码：

private ChronicleMap<String,RepositoryItem> repositoryMap;

repositoryMap=
            ChronicleMapBuilder
            .of(String.class, RepositoryItem.class).averageKeySize(KEY_SAMPLE.getBytes("UTF-8").length)
            .entries((long) (MAX_ENTRIES))
            .averageValueSize(1600)
            .create();

public void removeAllModified() {
    // This removes all the modified data from the repository
    Iterator iter=repositoryMap.values().iterator();
    // build a list of all the objects in the repository except the removed items
    while (iter.hasNext()){
        RepositoryItem repoItem=(RepositoryItem)iter.next();
        DataObject d = repoItem.getModified();
        if (d != null) {
            removeModified(repoItem);
        }
    }
}

有人能帮我解决这个错误吗。

Answer 1

Chronicle目前不支持运行Websphere的IBM。从您的消息中可以明显看出，Chronicle 2在IBM上失败了，因为它偶尔使用OpenJDK/OracleJDK中的一些类，但在IBM中却没有。

纪事地图3可能没有这个问题，因此潜在的解决方案可能是升级到Java 8和Chronicle 3。然而，这将是纪事地图3的一个附带属性，而且它也可能在以后的任何版本中停止与IBM一起工作。
