PyFlink module java.base does not "opens java.lang" to unnamed module

I want to run simple example from Flink documentation. And after start i got 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

Installed:

Python 3.10.6

openjdk version "19.0.2" 2023-01-17
OpenJDK Runtime Environment (build 19.0.2+7-Ubuntu-0ubuntu322.04)
OpenJDK 64-Bit Server VM (build 19.0.2+7-Ubuntu-0ubuntu322.04, mixed mode, sharing)

Simple code from flink site:

Solution

  • Flink doesn't support JDK 19, only 8 and 11.
