我正在尝试使用 OpenHFT ChronicleMap ,代码在 Tomcat 中运行,但在 Websphere 中失败并出现以下错误(如下)

注意:这不会在 Tomcat 中发生,仅在 Websphere 中发生。

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);
        }
    }
}

谁能帮我解决这个错误。

Chronicle Map 当前不支持运行 Websphere 的 IBM JVM。从您的消息中可以明显看出,Chronicle Map 2 在 IBM JVM 上失败了,因为它偶尔使用一些在 OpenJDK/OracleJDK 中存在但在 IBM JDK 中不存在的类。

Chronicle Map 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 Map 3。然而,这将是 Chronicle Map 3 的一个附带属性,并且它也可能在任何后续版本中停止与 IBM JVM 一起使用。
