PyFlink 模块 java.base 不"opens java.lang"未命名模块

Question

我想从Flink文档运行简单的例子。在start之后，我得到了exception:

Unable to make field private final byte[] java.lang.String.value accessible:
module java.base does not "opens java.lang" to unnamed module @228575c0

安装:

Python 3.10.6

Flink不支持JDK 19，只支持JDK 8和JDK 11。
