java - 使用 Java 15 启用持久性的 Apache Ignite 服务器节点（2.9.1）抛出异常

问题描述

例外：

[15:30:27,658][SEVERE][main][IgniteKernal] Exception during start processors, node will be stopped and close connections

点燃配置：

  public static IgniteConfiguration createConfiguration() {
    
    IgniteConfiguration cfg = new IgniteConfiguration();

    // Enabling peer-class loading feature.
    cfg.setPeerClassLoadingEnabled(true);

    DataStorageConfiguration dataStorageCfg = new DataStorageConfiguration();
    // Setting Persistence Enabled true
    dataStorageCfg.getDefaultDataRegionConfiguration().setPersistenceEnabled(true);
    cfg.setDataStorageConfiguration(dataStorageCfg);
    
    return cfg;
    
  }

尽管与 Java 8 和 11 相同的配置运行良好。

Java 15 中的PersistenceEnabled(false)也没有问题

解决方案

Ignite 仅在 Java 的 LTS 版本（即 Java 8 和 11）上进行了真正的测试。我会坚持使用这些版本。
