从 Java 8 迁移到 Java 11 - 无法加载 jdk.internal.util 类 (java.lang.NoClassDefFoundError)

Question

从 Java 8 迁移到 Java 11 打开 JDK。出现奇怪的错误，其中来自 java.base 模块的一个类 (java.util.Arrays) 无法从 java.base 模块访问另一个名为 (jdk.internal.util.ArraysSupport) 的类。

如果我查看 java.base 模块的模块信息 jdk.internal.util 包没有导出。我尝试了--add-export java.base/jdk.internal.util=ALL-UNNAMED，但得到了同样的错误。因为--add-export 有助于将包导出到另一个模块。这里的问题是来自同一模块的一个类无法访问来自同一模块的另一个类。不知道这里出了什么问题，正在寻找建议。

SalesHubSQLExecutionTasklet类的代码如下

@Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
    JdbcTemplate jdbcTemplate = new JdbcTemplate(this.getDataSource());

    long start = System.currentTimeMillis();
    try {
        if (!StringUtils.isBlank(this.getSql())) {
            if (this.getSql().toUpperCase().startsWith("UPDATE")) {
                int result = jdbcTemplate.update(this.getSql());
                LOGGER.info("{} records updated executing SQL [{}]", result, this.getSql());
            }
            else {
                jdbcTemplate.execute(this.getSql());
            }   
        }
        else if (this.sqls != null && this.sqls.length > 0) {
            int[] result = jdbcTemplate.batchUpdate(sqls);
            for (int i=0; i<sqls.length; i++) {
                LOGGER.info("SQL [{}] result [{}].", sqls[i], result[i]);
            }
        }
    }
    catch (Exception ex) {
        LOGGER.error("Error executing SQL [{}]", this.getSql(), ex);
    }
    LOGGER.info("Step {} execute SQL [{}] finished in {} ms.", chunkContext.getStepContext().getStepName(), this.getSql(), (System.currentTimeMillis()-start));

    return RepeatStatus.FINISHED;
}

第 45 行是

int[] result = jdbcTemplate.batchUpdate(sqls);

我试图在 Unix 机器上加载一个单独的普通类。而且效果很好

Class<?> classToLoad = Class.forName("jdk.internal.util.ArraysSupport");

它成功加载了类，所以不确定这里有什么问题！

我用最新的 Hikari 数据源替换了最新的 dbcp 数据源，它工作正常。谢谢大家的建议。
